Comparing Functions: Key Concepts and Techniques

The video tutorial covers comparing functions and rates of change in various contexts. It begins with an introduction to comparing functions represented in different ways, followed by exercises that involve ordering cyclists by speed, determining the winner of a hot dog eating contest, comparing bathtub draining rates, ordering cars by speed, and comparing exercises by calorie burn rate. Each section uses practical examples to illustrate the concept of rate of change and how it can be applied to solve real-world problems.
