i can't figure it out for some reason it's weird!

each limit represents the derivative of some function "f" at some number "a". state such an "f" and "a" in each case.

limit as x-->5

2^x - 32 / x-5

i keep trying but i can't get it right!

if it helps i know the answer in the back of the book says

f(x)=2^x, a=5

please and thank you!
