Only choose the pieces needed. Pupils learn a way to graph piecewise functions by graphing the entire function and then only keeping the section of the graph that belongs to the piecewise function. The Mathispower4u video shows three different examples using this method.

Instructional Ideas

• Provide several opportunities for the class to practice graphing piecewise functions
• Brainstorm where piecewise functions may appear in the real world

Classroom Considerations

• Requires the ability to graph linear and quadratic functions

• This video is hosted on YouTube

Pros

• Uses a graphing calculator to confirm the graphs
• Graphs each portion of the function with a different color to connect the graph with the equations

Cons

• None
