SOLUTION: f(x) = 2^x what is the inverse function f-1(x)= f(x)= log10 x what is the inverse function f-1(x)=

Question 805868: f(x) = 2^x
what is the inverse function f-1(x)=
f(x)= log10 x
what is the inverse function f-1(x)=
Answer by nikolatesla1(6) (Show Source): You can put this solution on YOUR website!
if f(x)=2^x, then f-1(x)=log(base 2)to the power of x
if f(x)=log10x, the f-1(x)=y, because log of 10 is 1,so therefore x=y, and y=x
