This time, try graphing three segments. Another Mathispower4u Algebra I Video provides an additional example on graphing a piecewise function. Pupils observe how to graph a function that is made from two constant functions and one linear function in slope-intercept form. The presenter graphs each rule and then restricts it to its defined domain.

Instructional Ideas

• Lead a discussion on whether piecewise functions are always non-continuous
• Develop a series of piecewise functions and let the class practice graphing them using the technique presented

Classroom Considerations

• Requires the ability to graph a linear function from slope-intercept form and constant functions

• This video is hosted on YouTube

Pros

• Uses colors to show the correspondence between the pieces of the graph and the individual function rules
• Demonstrates a method that is easy to follow and will work for all piecewise functions

Cons

• None
