Understanding Functions and Phone Usage

Curtis Brown and Robert Adoot introduce function notation using the context of phone hours as a function of days. They explain the concept with a vending machine metaphor and demonstrate it using a graphing calculator. The video explores calculations of phone usage over time and concludes with a recommendation to take programming classes to enhance understanding of functions.
