1. Use the graph for Parts A–D.
A. Is the relation a function? Explain.
B. What is the domain of the relation?
C. What is the range of the relation?
D. What is the value of y when x = 2? Explain.
- The relation is not a function due to multiple y-values for the same x-value.
- Domain: {-4, -3, 2}
- Range: {0, 2, -3}
- Value of y when x = 2: -1
Let's analyze the graph and address each part:
A. Is the relation a function? Explain.
- A function is a relation where each input (x-value) corresponds to exactly one output (y-value).
- Looking at the graph, we see that there are two different y-values for x = -3: (x = -3, y = 2) and (x = -3, y = -3).
- Since there are multiple y-values for the same x-value, the relation is not a function.
B. **What is the domain of the relation?
- The domain consists of all the x-values represented in the graph.
- From the graph, we can identify the following x-values: -4, -3, 2.
- Therefore, the domain of the relation is {-4, -3, 2}.
C. What is the range of the relation?
- The range consists of all the y-values represented in the graph.
- From the graph, we can identify the following y-values: 0, 2, -3.
- Therefore, the range of the relation is {0, 2, -3}.
D. What is the value of y when x = 2? Explain.
- To find the value of y when x = 2, we look at the graph.
- At x = 2, the corresponding y-value is -1.
- Therefore, the value of y when x = 2 is -1.

A player has 26 hits in 120 times at bat. Write the player's batting average as a decimal. Round to the nearest thousandth
Answer: 0.217
Step-by-step explanation:
Given : Number of hits = 26
Number of times at bat = 120
The formula to find the player's batting average is given by :-
[tex]\text{Player's batting average}=\dfrac{\text{Number of hits}}{\text{Number of times player at bat}}\\\\\Rightarrow\ \text{Player's batting average}=\dfrac{26}{120}\\\\\Rightarrow\ \text{Player's batting average}=0.216666666667\approx0.217\ \ \text{[ Rounded to the nearest thousandth]}[/tex]
Hence, the player's batting average = 0.217

Nathaniel's sister has 5/6 as many songs on her MP3 player as he has on his MP3 player. His sister has 35 songs. How many songs does Nathaniel have?
Answer:
42 songs.
Step-by-step explanation:
Let x represent the number of songs Nathaniel's has.
We have been given that Nathaniel's sister has 5/6 as many songs on her MP3 player as he has on his MP3 player. This means his sister has [tex]\frac{5}{6}x[/tex] songs.
We are also told that his sister has 35 songs. We can represent our given information in an equation as:
[tex]\frac{5}{6}x=35[/tex]
Let us solve for x.
[tex]\frac{6}{5}\cdot \frac{5}{6}x=\frac{6}{5}\cdot35[/tex]
[tex]x=6\cdot 7[/tex]
[tex]x=42[/tex]
Therefore, Nathaniel has 42 songs.

Step-by-step explanation:
where do young tigers swim
Young tigers, also known as tiger cubs, typically swim in bodies of water such as rivers, streams, lakes, and ponds found within their natural habitat.
Tigers are known to be excellent swimmers and are generally comfortable in water.
They use swimming as a means to cool off, explore their surroundings, and sometimes to hunt or catch prey.
Swimming also helps tiger cubs develop their physical abilities and gain confidence in the water.
Thus, it's important to note that tigers are found in various habitats across Asia, including mangrove swamps, grasslands, and forests, so the specific locations where tiger cubs swim may vary depending on their environment.

What is another way to write the ratio 3:4?
A teacher deposits $3,000 in a retirement fund. If she doesn't add any more money to the fund, which earns an annual interest rate of 6%, how much money would she have in 1 year?
After one year, the teacher would have $3,180 in the retirement fund without adding any more money to it.
To calculate the amount in the retirement fund after one year, we need to take into account the principal amount deposited and the interest earned over that period. The formula to calculate the total amount after one year is:
Total Amount = Principal Amount + (Principal Amount * Interest Rate)
Where:
Principal Amount = $3,000 (the initial deposit)
Interest Rate = 6% (expressed as a decimal, which is 0.06)
Now, we can plug the values into the formula:
Total Amount = $3,000 + ($3,000 * 0.06)
Total Amount = $3,000 + $180
Total Amount = $3,180

They y intercept of a function f(x) is (0,b) what is the y intercept of f(x)=k
The function f(x)=k represents a horizontal line where 'k' is the y-intercept. This means the line crosses the y-axis at the point (0,k).
Explanation:The function f(x)=k represents a horizontal line across the y-axis at the value of 'k'. In this case, the y-intercept or 'b' would also be 'k', given that regardless of the x-value, the output will always be 'k'. The point of intersection with the y-axis is thus (0,k).
In general, for the linear equation y=mx+b, 'm'
represents the slope of the line and 'b' is the y-intercept where the line crosses the y-axis. In this case, 'm' would be zero as the slope of a horizontal line is 0, causing the line's equation to simplify to
y=k, or f(x)=k. This indicates that for every x, the y value remains constant at 'k' .

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of donuts made be = A
The number of donuts made initially = 30 donuts
The time taken by the chef to make 30 donuts = 60 minutes
So , the equation will be
The number of donuts = 90 donuts
The number of donuts = 3 x initial number of donuts
So , the time taken by the chef to make 90 donuts is =
3 x time taken by the chef to make 30 donuts
And , the equation is
The time taken by the chef to make 90 donuts = 3 x 60 minutes
The time taken by the chef to make 90 donuts = 180 minutes
Therefore , the time taken by the chef is 180 minutes or 3 hours
Hence ,
The time taken by the chef to make 90 donuts is 180 minutes or 3 hours
