If you are given the graph of f, how do you find the graph of f-1?

Step-by-step explanation:

On the same set of coordinates on which f (x) has been graphed, graph the line y = x. Then reflect the graph of f (x) across the line y = x.

Note that this succeeds only if the graph of f (x) passes the "horizontal line test." Failure here means that there is no inverse function.
