Question

Which statement about this table of values is true?

A.Because the rate of change is constant, the function is linear
B.Because the rate of change is constant, the function is nonlinear
C.Because the rate of change is not constant, the function is linear
D.Because the rate of change is not constant the function is nonlinear

Answer 1

D.

Explanation:

Here the rate of change is not constant. For example:

10-5 / 20-17 = 5/3

13-10/23-20 = 3/3 = 1

Answer 2

D

Explanation:

If something is not constant we know it is non-linear. We know this is not constant because when graphed, the line is not straight.
