Question

Which function is nonlinear

Answer 1

Answer:

Only 3rd one is exponential and non linear.

Step-by-step 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.

Answer 2

the correct answer will be c.
