Taylor Russell's
inverse function applet provides a very nice visualization of the fact that the graph of an inverse function is obtained by switching the
x- and
y-coordinates of every point. You input the original function, so it is extremely flexible. As an added bonus, you can also plot the reciprocal function and see that it is not the same as the inverse. I used this applet in combination with
Emily Alman's Joe the Math Guy comic for my
most successful introduction to inverse functions ever.
