Answer:
f(1) = 2
Step-by-step explanation:
Since y is a function of x, that is;
y = f(x)
f(1) implies the value of y when x = 1.
To obtain this value we draw the vertical line x = 1 and check where the line intersects the graph of f(x).
In this case, the line x = 1 will intersect with the graph of f(x) on the line y = 2. The function f(x) assumes the value 2 between x = 0 and x = 4. Therefore,
f(1) = 2
Answer:
f(1) = 2

Which of the functions have a range of all real numbers? Check all that apply.
A. y = sec x
B. y = tan x
C. y = cot x
D. y = csc x
Answer:
B. y = tan x and C. y = cot x
Step-by-step explanation:
Range:
range is defined as the set of values that any given function y=f(x), can take for which the x values are defined. It is the value that y can take for the values of x.
Given:
From the given options
the range of tanx and cotx are all real numbers
as the period of tanx and cotx are π
where as range of secx is all real numbers except π/2 + n*π i.e.
(-∞ , -1] U [1 , + ∞)
And range of cscx is all real numbers except n*π i.e.
(-∞ , -1] U [1 , + ∞)
So from the given option:
option B and C are correct while A and D are not !
The answer is: The correct options are B. Tan(x) and C. Cot(x)
Why?The range is the output of a function when we evaluate the function with inputs (domain), not all functions have a range of all real numbers, however it's more common to find functions without range or domain restrictions.
Both options B. Tan(x) and C. Cot(x) have a range of all real numbers while the functions Sec(x) and Csc (x) have a restricted range.
Sec(x) and Csc(x):
Domain, all real numbers.
Range, from -1 to 1 or [-1,1]
Tan(x) and Cot(x):
Domain, all real numbers except [tex]\frac{\pi }{2}+-n\pi[/tex]
Range, all real numbers.
Hence, the correct options are B. Tan(x) and C. Cot(x)

the sum of two consecutive integers is -239 find the two integers
Answer:
The two consecutive integers are -119 and -120
Step-by-step explanation:
As we know that these two integers are consecutive, that means that they will have a difference of 1. This means that we can find the two integers by adding 1 to the sum of -239 and then dividing it by two
[tex]1-239=-238\\\frac{-238}{2} =-119\\-119-1=-120[/tex]
When needing to determine two consecutive integers with a given sum, they can be represented as 'x' and 'x+1'. The equation x + (x + 1) = -239 gives us the solution of the two integers as -120 and -119.
Explanation:In the given question, since we are dealing with consecutive integers, we can represent the integers as 'x' and 'x+1'. As per the information in the question, we know that the sum of these two consecutive integers is -239. Therefore, we can create the equation:
x + (x + 1) = -239
Solving this equation gives us:
2x + 1 = -239
Therefore,
2x = -240
So, x = -120
This indicates that our first integer is -120. Because we are dealing with consecutive integers, the next integer would be -120 + 1 = -119. Thus, the two consecutive integers are -120 and -119.

An angle in standard position measures -7x/6 radians. In which quadrant does the terminal side of this angle lie
The terminal side of an angle measuring -7x/6 radians lies in the second quadrant, considering the angle implies a clockwise rotation from the positive x-axis and one complete rotation is 2π radians.
One complete revolution is equal to 2π radians, which is approximately 6.28 radians. Negative angles imply a clockwise rotation from the positive x-axis. The given angle, -7x/6 radians, would place the terminal side in a clockwise rotation from the positive x-axis.
Angles that measure between 0 to -π/2 radians lie in the fourth quadrant, while angles between -π/2 to -π radians lie in the third quadrant, angles between -π to -3π/2 radians lie in the second quadrant, and angles between -3π/2 to -2π radians lie in the first quadrant.
Assuming the variable x represents any positive real number, the angle -7x/6 would likely be between -π and -3π/2 (or -1.57 and -4.71), and therefore, the terminal side of this angle would lie in the second quadrant.
What is the solution set of {x | x < - 5} n {x | x > 5} ?
a. all numbers less than -5 and greater than 5
b. the numbers between -5 and 5
c. the empty set
d. all real numbers
Answer:
c. the empty set
Step-by-step explanation:
set of {x | x < - 5} n {x | x > 5}
The set x < - 5 comprises of real numbers that are less than -5;
(-6, -7, -8, -9, -10, -11, ......)
On the other hand, the set x > 5 comprises of real numbers greater than 5;
(6, 7, 8, 9, 10, 11, ......)
Clearly, the intersection of the above sets is empty, in that the intersection has no elements.
Therefore, {x | x < - 5} n {x | x > 5} is an empty or null set
Answer:
The solution set empty set or null set ⇒ answer c

* Lets study the meaning of the inequality
- If a < x < b, that means the value of x is between a and b
- If a ≤ x ≤ b, that means the value of x is from a to b
- If x < a and x > b, that means the value of x is smaller than a and
grater than b
- If x ≤ a and x ≥ b, that means the value of x is smaller than or equal a and
grater than or equal b
* Now lets solve the problem
∵ {x I x < -5}
∴ x is smaller than -5
∵ {x I x > 5}
∴ x is greater than 5
∵ {x I x < -5} ∩ {x I x > 5}
- The meaning of ∩ is the common numbers between the
two sets, but there is no common numbers between the
two sets
∴ {x I x < -5} ∩ {x I x > 5} = { }
∴ The solution set empty set or null set
What is the axis of symmetry for the graph of y - 4x = 7 – x2?
O x= 2
Oy=2
O x= 11
Oy= 11
Answer:
x = 2 is the axis of symmetry
Step-by-step explanation:
y - 4x = 7 – x2?
y = -x²+4x +7
y = - ((x²- 4x+4)-4)+7
y = - (x-2)²+11 ..... is the the parabola's equation when : x = 2 is the axis of symmetry
The axis of symmetry for the graph of y - 4x = 7 – x² is x= 2.
What is axis of Symmetry?The axis of symmetry is a hypothetical straight line that divides a shape into two identical sections, resulting in one component being the mirror image of the other. When folded along the axis of the symmetry, the two portions get overlaid. The straight line is also known as the line of symmetry/mirror line.
The axis of symmetry is a straight line that makes an object's shape symmetrical. The axis of symmetry produces identical reflections on all four sides. It might be horizontal, vertical, or lateral in orientation.
We have the Equation:
y - 4x = 7 – x²
Now, arranging the equation as
y = -x²+4x +7
y = - ((x²- 4x+4)-4)+7
Now, using the algebraic Identity
(a -b)² = a² - 2ab + b²
So, the equation can be written as
y = - (x-2)²+11
This is in the parabola's equation.
Thus, the axis of symmetry is x= 2.

The recursive rule for a sequence is a^n=a^(n-1)+7,where a^1=-15. What is the explicit rule for this sequence?
ANSWER
[tex]a_n=7n - 22[/tex]
EXPLANATION
The recursive rule for the sequence is
[tex]a_n=a_{n-1}+7[/tex]
In general the recursive rule is written as:
[tex]a_n=a_{n-1}+d[/tex]
This implies that, d=7
The first term of the sequence is
[tex]a_1= - 15[/tex]
The explicit rule is given by:
[tex]a_n=a_1 + d(n - 1)[/tex]
We substitute to get;
[tex]a_n= - 15 + 7(n - 1)[/tex]
[tex]a_n= - 15 + 7n - 7[/tex]
[tex]a_n=7n - 22[/tex]

b. closed circles on 1 and 4 with arrows pointing outward
c. the entire number line
d. no solution
Answer:
b. closed circles on 1 and 4 with arrows pointing outward
Step-by-step explanation:
Which of the following describes the graph of {x | x < = 1} u {x | x > = 4},
We have been given the following set;
x < = 1
This set comprises of real numbers that are less than or equal to 1;
(1, 0, -1, -2, -3, -4, .......... -∞)
On the other hand, the set x > = 4 comprises of real numbers that are greater than or equal to 4;
(4, 5, 6, 7, 8, 9, ........∞)
The symbol ∪ means a union of sets. That is the set of numbers that belong in either or both sets;
{x | x < = 1} u {x | x > = 4} is same as writing;
(1, 0, -1, -2, -3, -4, .......... -∞) ∪ (4, 5, 6, 7, 8, 9, ........∞)
Therefore, the solution set will be closed circles on 1 and 4 with arrows pointing outward
Answer:
Closed circles on 1 and 4 with arrows pointing outward ⇒ answer b
Step-by-step explanation:
* Lets study the meaning of the inequality
- If a < x < b, that means the value of x is between a and b
- If a ≤ x ≤ b, that means the value of x is from a to b
- If x < a and x > b, that means the value of x is smaller than a and
grater than b
- If x ≤ a and x ≥ b, that means the value of x is smaller than or equal a and
grater than or equal b
* Now lets solve the problem
∵ {x I x ≤ 1}
∴ x is smaller than or equal 1
∵ {x I x ≥ 4}
∴ x is greater than or equal 4
∵ {x I x ≤1} ∪ {x I x ≥ 4}
- The meaning of ∪ is all numbers smaller than or equal 1 and all
the numbers greater than or equal 4
∴ {x I x ≤ 1} ∪ {x I x ≥ 4} = (-∞ , 1] ∪ [4 , ∞)
- This solution represented graphically by closed circles on 1 and
4 with arrows pointing outward
solve (1/64)^0.5x-3 =8^9x-2
Answer:
0.8
Step-by-step explanation:
You are given the equation
[tex]\left(\dfrac{1}{64}\right)^{0.5x-3}=8^{9x-2}[/tex]
First note that
[tex]\dfrac{1}{64}=\dfrac{1}{2^6}=2^{-6}\\ \\\left(\dfrac{1}{64}\right)^{0.5x-3}=(2^{-6})^{0.5x-3}=2^{-6\cdot (0.5x-3)}=2^{-3x+18}\\ \\8=2^3\\ \\8^{9x-2}=(2^3)^{9x-2}=2^{3\cdot (9x-2)}=2^{27x-6}[/tex]
Now
[tex]2^{-3x+18}=2^{27x-6}\\ \\-3x+18=27x-6\\ \\-3x-27x=-6-18\\ \\-30x=-24\\ \\x=\dfrac{24}{30}=\dfrac{8}{10}=0.8[/tex]
Final answer:
To solve the given equation, we convert both sides to a common base and equate the exponents. After simplifying, we find that the solution is x = 8/11.
Explanation:
We are asked to solve the equation (1/64)^0.5x-3 = 8^9x-2. To begin, we will express both sides of the equation with the same base since 64 is 2^6 and 8 is 2^3. This transformation will allow us to use the property of exponents that states when the bases are equal, the exponents must also be equal.
First, let's rewrite the equation using base 2:
(1/2^6)^(0.5x-3) = (2^3)^(9x-2)(2^-6)^(0.5x-3) = (2^3)^(9x-2)2^(-6(0.5x-3)) = 2^(3(9x-2))Now, since the bases are the same, we can equate the exponents:
-6(0.5x-3) = 3(9x-2)-3x + 18 = 27x - 633x = 24x = 24/33x = 8/11The solution to the equation is x = 8/11. Always remember to check for extraneous solutions when dealing with exponents and roots.
