The inverse of this function is f(x) = [tex] \sqrt[3]{x - 6} [/tex]
You can find the value of any inverse function by switching the f(x) and the x value. Then you can solve for the new f(x) value. The end result will be your new inverse function. The step-by-step process is below.
f(x) = x^3 + 6 ----> Switch f(x) and x
x = f(x)^3 + 6 ----> Subtract 6 from both sides
x - 6 = f(x)^3 ----> Take the cube root of both sides
[tex] \sqrt[3]{x - 6} [/tex] = f(x) ----> Switch the order for formatting purposes
f(x) = [tex] \sqrt[3]{x - 6} [/tex]
And that would be your new inverse function.

Point Q is the midpoint of GH. GQ=2x+3, and GH=5x−5 .
What is the length of GQ?
Enter your answer in the box.
____ units
The length of GQ is 25/3 units.
Explanation:To find the length of GQ, we need to equate GQ to GH and solve for x. Since Q is the midpoint of GH, the lengths GQ and QH are equal. Therefore, we have the equation:
2x + 3 = 5x - 5
Subtract 2x from both sides:
3 = 3x - 5
Add 5 to both sides:
8 = 3x
Divide both sides by 3:
x = 8/3
To find the length of GQ, substitute the value of x back into 2x + 3:
GQ = 2(8/3) + 3
GQ = 16/3 + 3
GQ = 16/3 + 9/3
GQ = 25/3 units

The ages of mark and adam add up to 28 years total. mark is 20 years older than adam. how many years old is adam
Adam is 4 years old. This conclusion is reached by setting up a system of equations based on the information that Mark and Adam's ages add up to 28 years and Mark is 20 years older than Adam.
The student is asking how old Adam is, given that the total age of Mark and Adam is 28 years, and Mark is 20 years older than Adam. To solve this, we can set up a system of equations. Let Mark's age be represented by M and Adam's age be represented by A. The two equations based on the given information would be:
M + A = 28 (The sum of their ages is 28)M = A + 20 (Mark is 20 years older than Adam)Now, substituting the second equation into the first one, we get:
A + 20 + A = 28
This simplifies to:
2A + 20 = 28
Subtracting 20 from both sides, we have:
2A = 8
Dividing both sides by 2, we find:
A = 4
So, Adam is 4 years old.
which shows the set(s) the number 2.77 is an element of?
The correct answer is option a. 2.77 is an element of the set real numbers.
To determine which set(s) the number 2.77 is an element of, let's analyze each option:
1. Real numbers: The set of real numbers includes all rational and irrational numbers. This means any number that can be placed on the number line, including integers, fractions, and decimals. Since 2.77 is a decimal number, it is indeed a real number.
2. Real numbers and natural numbers: While 2.77 is a real number, natural numbers are a subset of real numbers that consist of all positive integers (1, 2, 3, ...). Since 2.77 is not a positive integer, it is not a natural number. Therefore, this option is incorrect because 2.77 is not a natural number.
3. Natural numbers and whole numbers: As mentioned, natural numbers are positive integers. Whole numbers include all natural numbers and the number 0 (0, 1, 2, 3, ...). Since 2.77 is neither a natural number nor a whole number, this option is incorrect.
4. Null set: The null set (or empty set) contains no elements. If 2.77 were in the null set, it would imply that the null set is not empty, which contradicts the definition of the null set. Therefore, this option is incorrect.
The complete question is
"Which shows the set(s) the number 2.77 is an element of?
a. real numbers
b. real numbers and natural numbers
c. natural numbers and whole numbers
d. null set"

y =
x +
The slope intercept equation which models the data in the table given ls y = 3x + 1
General form of a slope - intercept equation :
y = bx + c ; b = slope ; c = interceptSlope can be calculated thus:
Slope = (y2 - y1) /(x2 - x1)
Slope = (-2 + 8) / (-1 + 3)
Slope = 6/2 = 3
Taking any pair of points, we can calculate the intercept, c :
y = 3x + c
10 = 3(3) + c
10 = 9 + c
c = 10 - 9
c = 1
Therefore, the slope - intercept equation is y = 3x + 1

Given : Function [tex]y=2x^2-12x+21[/tex]
To find : Determine the axis of symmetry and the vertex of the given function.
Solution :
The quadratic function is in the form, [tex]y=ax^2+bx+c[/tex]
On comparing, a=2 , b=-12 and c=21
The vertex of the graph is denote by (h,k) and the formula to find the vertex is
For h, The x-coordinate of the vertex is given by,
[tex]h=-\frac{b}{2a}[/tex]
[tex]h=-\frac{-12}{2(2)}[/tex]
[tex]h=\frac{12}{4}[/tex]
