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.

To find an inverse function, the equation is rearranged to change the subject and use inverse processes. For example, for a function that multiplies by 3 and subtracts one, the inverse function is ...

To find an inverse function, form an equation by giving the output value a name using a letter (such as y), then rearrange the equation to make x the subject.

The sample inverse autocorrelation function (SIACF) is estimated in the ARIMA procedure by the following steps. A high-order autoregressive model is fit to the data by means of the Yule-Walker ...
