You can  put this solution on YOUR website! (a) Find the domain and range of the function f(x) = log(8x). 
---- 
Domain? 
8x must be >0, so x must be > 0 
----------- 
Domain: All real Numbers greater than zero. 
================================================== 
  
(b) Find the inverse of f(x) = log(x). 
Interchange x and y to get: 
x = log(y) 
Solve for "y": 
y = 10^x 
-------------- 
f -1(x) = 10^x 
==================================================
