Question

Which functions are nonlinear? Choose all answers that are correct.

Answer 1

A non linear function would be a function that is not a straight line. So in this case it would be the squiggly lines that are the nonlinear functions. 

Answer 2

A nonlinear function does not follow a straight line. 

Here, we can see only two that do not follow a straight line. 

Answers:-

- The first graph does not show a straight line, therefore, it is nonlinear.
- The third graph does not show a straight line, it is also nonlinear.
