Answer:

Last option

Function A is non-linear and Function B is linear

Step-by-step explanation:

The equation for Function B is y = -x + 5

This is the slope-intercept form of a line. Here slope is -1 and y-intercept is 5

We can eliminate the first two options

Function A is clearly non-linear. In fact it is a cubic function of the form
y = x³

0³ = 0

1³  = 1

2³ = 8

3³ = 27
