Graphing Piecewise Functions: Key Concepts and Examples

This video tutorial teaches viewers how to graph piecewise functions through a series of examples. Starting with simpler functions and progressing to more complex ones, the video covers graphing techniques for linear and quadratic functions within piecewise contexts. The instructor provides detailed explanations and visual aids to help viewers understand the process. The video concludes with a practice problem for viewers to solve and encourages engagement through comments.
