Functions and Relations

Description

Environmentalists, meteorologists, economists, and people in many other disciplines have always been interested in the dynamics of variables, or quantities that change-for example, the number of polar bears that inhabit a certain region during the summer, or the number of tickets sold during a movie's first weekend in theaters. Functions are indispensible to that kind of sampling since they represent relationships between variable quantities. Hosted by internationally acclaimed math educator Dr. Monica Neagoy, this program offers guidance in the notation of functions and distinguishes the concept of function from a general relation. Demonstrations of functions are provided using the TI-Nspire graphing calculator. The video covers quadratic functions, linear functions, and multiple representations.
