Learn about function notation, how to find an inverse function by changing the subject, and how to work with composite functions.

An inverse function graphing calculator will allow you to graph functions quickly and precisely, which will help you visualize how these graphs behave.

The sample inverse autocorrelation function (SIACF) plays much the same role in ARIMA modeling as the sample partial autocorrelation function (SPACF) but generally indicates subset and seasonal ...
