Concept

Function Family

Functions with similar characteristics can be grouped together in what is known as a function family. By applying one or several transformations to a parent function, it is possible to construct any function in its function family. The most common function families are linear functions, absolute value functions, quadratic functions, and exponential functions.

There are also several other function families such as square root functions, cubic functions, rational functions, and logarithmic functions.
