Question: how to find the inverse of a function for dummies?
Answer: Switch f(x) and x. When you switch f(x) and x, you get. (Note: To make the notation less clumsy, you can rewrite f(x) as y and then switch x and y.)
Change the new f(x) to its proper name — f–1(x). The equation then becomes.
Solve for the inverse. This step has three parts:
