I would just like help understanding this please.

I'm sure you meant $f(x)\color{red}{=}b^x$, not +.

$f(x)$ is a function containing an EXPONENT. What does that tell you?

anonymous · Answer

I'm not sure.  I think you would use square root to figure it out. does that mean A?

anonymous · Answer

No, a square root function would look like this: $f(x)=\sqrt{\cdots}$, or $f(x)=(\cdots)^{1/2}$, which has a CONSTANT exponent.

For $b^x$, we have $x$ in the exponent, and thus a VARIABLE exponent.

Oh, duh... EXPONENT, EXPONENTIAL. Okay. so B...

anonymous · Answer

Yes!
