Question

Which function is nonlinear

Answer 1

the correct answer will be c.

Answer 2

Only 3rd one is exponential and non linear.

Explanation:

Linear functions are in the form of
`y=mx+c` and have a constant slope.

Nonlinear functions have a slope that varies between points.

Also, the linear functions are polynomials with highest exponent equal to 1 and all others are non linear.

Here, only option 3rd is not linear or non linear.

Other options are all in the form of
`y=mx+c` means linear.

Only 3rd one is exponential and non linear.
