Determine a Basic Piecewise Defined Function

Curated and Reviewed by Lesson Planet

Not all functions have the same equation throughout. Learners see a word problem that requires more than one equation to model the situation. The video from the Mathispower4u Algebra 1 series introduces the concept of piecewise defined functions that allow for one function to model the situation. Scholars find out that different domains may each have their own equations to define that section of the function.

Instructional Ideas
  • Have individuals create word problems that should be represented by piecewise functions
Classroom Considerations
  • Assumes pupils understand the domain of a function
  • Requires the class to know how to write simple linear functions
  • This video is hosted on YouTube
Pros
  • Does not require knowledge of piecewise functions
  • Provides a graph of the function and labels each section of the graph with its corresponding equation
Cons
  • None
