Miss Doolittle explains how to identify linear and nonlinear functions using tables, graphs, and equations. She provides a checklist for determining linearity, emphasizing constant rates of change in tables, straight lines in graphs, and specific conditions in equations. The video covers how to recognize nonlinear functions by identifying inconsistencies in these areas.

What are the three methods to determine if a function is linear or nonlinear?

• Table, Graph, and Equation

• Table, Graph, and Chart

• Graph, Equation, and Diagram

• Equation, Chart, and Diagram
