Families of Functions: Explore 150+ Videos That Illustrate How to Graph Parent Functions and Their Transformations

When: Tuesday, January 12, 2021 | 7 p.m. Central time
Technology: TI-84 Plus family, TI-Nspire™ CX technology
Presenter: Tom Reardon

Find out how to use this treasure trove of modular videos, and tailor the learning to your students and course needs. The colorful, animated videos show how to graph each of 13 parent functions.

Each parent function is also graphed using six different transformations:
  • y = f(x) + a
  • y = f(x + a)
  • y = a*f(x)
  • y = f(-x)
  • y = -f(x)
  • y = f(a*x)
  • and combinations of these transformations
This content is compatible with the TI-84 Plus family of graphing calculators or TI-Nspire™ technology. All materials are free and online — ideal for review, remote learning, independent learning and in-class learning. The topics are appropriate for grades 8–12.
