How to Graph Piecewise Functions Step-by-Step

Miacademy & MiaPrep Learning Channel

This instructional video provides a comprehensive guide to graphing piecewise functions, covering both fundamental concepts and practical graphing strategies. The lesson begins by defining a piecewise function as a function defined by at least two equations, each applying to a different part of the domain. It distinguishes between the "eraser method"—graphing the entire function and removing unwanted parts—and a more efficient table-based method that focuses strictly on the restricted domain values.
