Definition
A function is linear if there is a single unique x that corresponds to each y.
Linear
$ y=e^x $
This function is linear because for each y value has only one corresponding x value.
Nonlinear
$ y=x^4 $
This function is not linear because for every y value there are two possible x values that could produce the same result.
