which table represents a nonlinear function?

x y
1 20
2 18
5 12
9 4

x y
0 0
1 3
3 9
7 21

x y
0 0
1 1
4 16
7 49

x y
−3 0
−1 −2
2 −5
6 −9

Step-by-step explanation:

xy

−30

−1 −2

2 −5

6 −9 is a nonlinear

because when you plot the points given x=-3 y=0 and x=-1 y=-2 are found in the 3rd quadrant and the rest are found in the 4th quadrant.

which will not make the points linear

Hope this will help

c is the correct answer
