Teaching Topics Efficiently: Domain and Range of Functions From Algebra Through Calculus

When: Tuesday, March 15, 2022 | 7 p.m. Central time
Technology: TI-84 Plus family, TI-Nspire CX technology
Presenters: Ray Barton, Diane Broberg

Students begin to work with domains and ranges in algebra and continue this through their high school courses.

Domain and range are foundational concepts in mathematics, yet sometimes students struggle to understand and describe them. Join this webinar as we demonstrate how graphing technology facilitates student interaction with functions in a way that leads to visualization and comprehension of domain and range. We will look at domain restrictions in real-world problems as well as continuous, discrete, composite and piecewise functions. We will include features from both the TI-84 Plus CE and TI-Nspire™ CX families of graphing calculators.

"I liked learning new things that my calculator can do. I am pretty proficient but I did learn quite a few new tricks." — Julie Rickard, American Leadership Academy (Arizona)
