    This lesson goes through some more examples of finding the inverse of functions. Also, the graphs of a function and its inverse are examined and discussed. Some of the functions are more complicated than just lines. All steps and explanations are very clear. This is a must-watch if you are having difficulty computing the inverse of functions.
