Answer
Use the image to answer the question.
An illustration shows a coordinate plane with four quadrants. The x and y axes range from negative 6 to 6 in increments of 1. A semicircle is graphed on the plane. The semicircle passes through points plotted at coordinates left parenthesis 0 comma 6 right parenthesis, left parenthesis 6 comma 0 right parenthesis, and left parenthesis 0 comma negative 6 right parenthesis.

To find the output of the function y=−3x−7 when the input is −5, simply substitute -5 for x in the equation and solve for y:

y = -3(-5) - 7
y = 15 - 7
y = 8

So, the correct output is 8.

To find the value of the function y=3x^2−21 when x=4, we substitute 4 for x in the equation and solve for y:

y = 3(4)^2 - 21
y = 3(16) - 21
y = 48 - 21
y = 27

So, the value of the function is y = 27.

Based on the given information, since a semicircle is graphed, it passes the vertical line test. Therefore, the relation is a function. Hence, the answer is 1.
Answered by GPT 3.5
The function y=x^5−13 is a nonlinear function. Therefore, the answer is 2.
