Check it outFinding an Inverse Algebraically  Problem 9 275 views
Any time we're asked to find the inverse of a function, we need to switch x and y and then solve for y. When asked to find the inverse of a exponential function in particular, we'll be needing to rewrite the function in log form using the definition of logs. You must be extremely careful when you're rearranging the quantities to make sure everything ends up in the right place. "ln," or the natural log, can be thought of as log base "e." Don't forget to check your work using compositions, making sure that f(f1(x)) = f1(f(x) = x .
