Break it up into pieces to solve the problem. Individuals watch a video on how to graph and determine the equation and values of piecewise functions. Viewers then work several exercises to practice evaluating a piecewise function at given points in its domain, graphing piecewise functions, and writing equations from graphs.

Concepts

piecewise functions, graphing functions, functions, graphing linear equations, graphing quadratics, range

Instructional Ideas

• Remind the class how to graph inequalities

Classroom Considerations

• Third lesson in a five-part Algebra I Unit 8 series
• The class should know how to tell whether or not a graph is a function

Pros

• Uses colors to show the different pieces of the graphed function
• Provides detailed answer keys

Cons

• None
