Me ! which table represents a nonlinear function? x y 0 0 1 1 4 16 7 49 x y −3 0 −1 −2 2 −5 6 −9 x y 0 0 1 3 3 9 7 21 x y 1 20 2 18 5 12 9 4

Remark
We have to figure out which of the graphs is not linear if they were graphed.

Eliminations
The last one is the graph of 
y = 22 - 2x which is still a straight line.
D is linear.

The second last one is the table for
y = 3x which is a straight line going through the origin.

The second from the top is not easily deciphered. 
The line I get is y = - x - 3 which is linear or a straight line.

The top one is
y = x^2 which is not linear at all
Answer A <<<<<

What are the following algebraic equations. you need to post those if you want the answer

$7.50x+$4.50y=midk it's been awhile since i've done one of these
