Parent Function

A function family is a group of functions that have similar characteristics. A parent function is the most basic function in a function family. The most common parent functions are those of linear functions, absolute value functions, quadratic functions, and exponential functions.

Other types of functions also have their corresponding parent functions. The parent functions of square root functions, cubic functions, rational functions, and logarithmic functions are shown in the applet below.
