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
