Comparing Function Properties Across Different Representations

This video tutorial teaches how to compare properties of functions represented in various forms, such as equations, graphs, tables, and verbal descriptions. It explains how to determine key properties like slopes and intercepts from each representation. The video includes examples comparing different functions to illustrate these concepts, helping viewers understand how to analyze and compare functions effectively.

Which of the following is NOT a way to represent a function?

• Graph

• Matrix

• Table of values
