The video tutorial explains how to graph functions by using tables and recognizing symmetry properties. It covers even functions, which are symmetric about the y-axis, and odd functions, which are symmetric around the origin. The tutorial also discusses symmetry in non-function graphs, such as circles, which can have multiple symmetry properties. Understanding these concepts helps in graphing functions more efficiently.

What is one method to graph a function that will always give at least a rough sketch?

• Using a computer program

• Drawing freehand

• Making a table of values

• Using a calculator

Why are even functions called 'even'?

• Because they are symmetric with respect to the origin

• Because they have even coefficients
