Question

Is the function described by the points in this table linear or nonlinear?

x            y

-3          9

-1           1

0              0

1              1

3              9

A) Linear

B) Non-Linear

Answer 1

Nonlinear

Explanation:

I took the k12 test and I have proof.

Answer 2

Find out the differences between consecutive numbers of both series.
x = 2, 1, 1, 2
y = 8, 1, 1, 8

Here, you can see it's not varying with constant degree. So, your answer would be "Non-Linear"

Hope this helps!
