Modeling the Equation of a Piecewise Defined Function from Its Graph

Build a function from pieces of other functions. Learners observe how to write a piecewise function from its graph with an instructive video. The video uses all notation and vocabulary related to piecewise functions, as well as a linear example with three parts.

Instructional Ideas

  • Give learners a similar problem to complete while they are watching the video
Classroom Considerations

  • Pupils should be familiar with the concept of domain and writing linear equations
  • Requires Internet access to watch the YouTube video
  • The lesson follows seven others in a sequence of 29 videos related to functions.
Pros

  • The lesson is separated into sections, making it easy to follow 
  • The use of color facilitates a connection between the graph and the related funtions
Cons

  • The lesson only uses one linear example
