Graphing Piecewise and Step Functions
Concept

Step Function

A step function is a piecewise function that is defined by a constant value on each part of its domain. As an example, consider the following function.
The graph of a step function consists of horizontal line segments, which can be interpreted as steps. The graph of the given function has four line segments.
Step Function Example

Another common example of a step function is the Greatest Integer Function.
