The customary method of finding the inverse is some variant of the method I'm going to use below. Whatever method you use, make sure you do the exact same steps in the exact same order every time, so you remember those steps when you get to ... There will be times when they give you functions that don't have inverses.

Many students in high school and in college have a difficult time with the concept of inverse functions: what they are, when they exist, how they are used, how to calculate them, how to graph them, and how to interpret their findings.

Thus, the inverse of a function is a function that looks at this relationship from the other viewpoint. So, ... When we graph functions and their inverses, we find that they mirror along the line x=y. This is only logical. From our definition, we know that for each (a,b) in f(x) there will be a (b,a) in f-1(x):

Objectives: In this tutorial, we define the inverse of a function. We discuss three different ways of determining whether a function has an inverse. Some examples are discussed. After working through these materials, the student should be able ... Drill in finding the inverses of functions.
