Mrs. Hayes introduces graphing functions, focusing on linear, absolute value, and quadratic functions. She explains how to use function rules to complete tables of values and plot graphs. The video covers calculating values for each function type and plotting them to visualize the graph's shape, including lines and parabolas.

What are the learning goals mentioned in the introduction?

• Using a function rule to complete a table of values and plot it on a graph

• Solving quadratic equations

• Learning about trigonometric functions

• Understanding the Pythagorean theorem
