Question

What is the difference between an exponential and a non-exponential function?

Answer 1

I think its that the x is not the exponent

Answer 2

You're on the right track. Soooooo
\[e^{x}\] would be an exponential function.

And something like f(x) = x+2 would not be.

Answer 3

Exponential functions have variables raised to an exponent. Exponential graphs usually have a wide curve that is not a straight line.

Example of exponential function: y = 3^x

Answer 4

exponential function contains \[a^{x}\] other than this are non exponential
