Precalculus: Rational Functions

by Texas Instruments


  • Students will explore the relationship between rational functions and both vertical and horizontal asymptotes. They will examine these relationships graphically and algebraically.
  • Students will be asked to create sliders on the handheld to help in their exploration and discussions.
  • Students will try to make a connection with how to understand these topics in IB Mathematics courses and on their final assessments.


  • Sliders
  • Vertical Asymptotes
  • Input
  • Output
  • Horizontal Asymptotes

About the Lesson

Students will create a TI-Nspire file to dynamically examine the rational functions generated by quotients of linear functions.

*Note: This activity includes optional IB support, including the IB Questions download for students who are preparing for the IB Exam.
