Question

Which one of these is an exponential function?

1. f(x) = 2(x + 4) + 3
2. h(x) = xz -8
3. f(x) = 3x + 5
4. g(x) = 2x +2​

Answer 1

None of them are

Explanation:

None are exponential they are all linear, exponential has an exponent in it, and is a gradually increasing curve. These are all straight lines of varying slope and such.

I would go with 2, most room for some kind of something
