Answer:

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.
