Question

Is the function linear or nonlinear?

Answer 1

Non-linear

Explanation:

X Y

7 20

8 11

9 4

When you go from 20 to 11, you subtract 9.

However, when you go from 11 to 4, you only subtract 7.

Therefore, it is not linear.

Answer 2

the function is nonlinear, as the y-values do not go down at the same rate.
