A. The first way to solve an inverse function is to graph it by hand or on your graphing calculator. To graph by hand, plot the original function and then reflect its coordinates over the line y = x.

Inverse functions An inverse function links the output value back to the input value, meaning it is the original function in reverse. An inverse function is written as 𝑓\ (^-\)\ (^1\) (𝑥).

Foutz (1977) uses the Inverse Function Theorem to prove the existence of a unique and consistent solution to the likelihood equations. This note extends his results in three useful directions. The ...
