What is the primary difference between exponential and linear functions?
Yanka [14]

Answer:

A

Step-by-step explanation:

We know that the growth of a linear function will always be constant. So, that eliminates B and C.

A quadratic function can be a function such as x^2, or 5x^2+7x, etc.

An exponential function wouldn't be x^2, it would be 2^x! Or 3^x, or (1.738283)^x, etc. Therefore, D is eliminated.

So, the answer is \boxed{A} and we're done!
