To find the output of the function y = -3x - 7 when the input is -5, substitute -5 for x in the function and solve for y.
y = -3(-5) - 7
y = 15 - 7
y = 8
The correct output is 8.

To find the value of the function y = 3x^2 - 21 when x = 4, substitute 4 for x in the function and solve for y.
y = 3(4^2) - 21
y = 3(16) - 21
y = 48 - 21
y = 27
The value of the function y = 3x^2 - 21 when x = 4 is 27.

The given function y = x^5 - 13 is a nonlinear function.
To determine if a function is linear or nonlinear, we examine the power of the variable. In this case, the power of x is 5, which is greater than 1. Therefore, the function is nonlinear.
Enter 2 if the function is nonlinear.
Graph of a Function Practice Complete this assessment to review what you've learned. It will not count toward your grade. 1 of 51 of 5 Items Question Determine if (3,0.75) is a point on the graph of the function y=0.75x−1.5 . Enter 1 for yes. Enter 2 for no.(1 point) Skip to navigation page 23 of 24
To determine if (3, 0.75) is a point on the graph of the function y = 0.75x - 1.5, substitute x = 3 into the equation and see if it satisfies the equation.
y = 0.75(3) - 1.5
y = 2.25 - 1.5
y = 0.75
Since the calculated value of y is 0.75, which matches the y-coordinate in the given point (3, 0.75), we can conclude that (3, 0.75) is a point on the graph of the function.
Enter 1 for yes.
