Graphing Piecewise Functions: Key Concepts and Practice

This video tutorial focuses on graphing piecewise functions through various examples. It begins with a simple piecewise function and progresses to more complex ones involving linear, quadratic, and rational components. The tutorial explains how to graph each segment of the piecewise function, using open and closed circles to indicate included and excluded values. By the end, viewers will understand how to graph different types of piecewise functions step by step.
