by Texas Instruments

Objectives

The purpose of this activity is for students to gain a greater understanding of functions and their inverse, specifically looking at where the points of intersection occur between the original function and its inverse. The investigation also tries to break some of the misconceptions relating to where functions and their inverses intersect. 

Vocabulary

  • Function
  • Inverse
  • Domain
  • Range
  • Intersection
  • Reflection
