Why is this function nonlinear?

• This function is nonlinear because it has a constant rate of change.

• This function is nonlinear because it does not have a constant rate of change.

• The function is nonlinear because the y-intecept is (0,1)

• This function is nonlinear because there is a coefficient of 4.
