SOLUTION: How would I find the inverse of f(x)=log 9 (x)? Does having the parenthesis around x change it?
Here is what I did:1) re-write it as y=log 9 (x); 2) identify 9 as the base, y a

Question 684125: How would I find the inverse of f(x)=log 9 (x)? Does having the parenthesis around x change it?
Here is what I did:1) re-write it as y=log 9 (x); 2) identify 9 as the base, y as the exponent, and keeping x on the right side of the equation; 3) re-write it as 9^y=x. Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! The inverse of the log function is the exponential form:
For given problem:y=log 9 (x)
Exponential form: base(9) raised to log of number(y)=number(x)
9^y=x
so, you were right on.
