Learn the Steps to Graph Piecewise Functions

The video tutorial explains piecewise functions, which are functions composed of multiple sub-functions, each defined over a specific domain. The instructor demonstrates how to graph these functions by treating each sub-function separately and then combining them. The tutorial also covers the concepts of domain and range, emphasizing the importance of understanding how open and closed circles affect the graph. The video concludes with a discussion on how to represent these functions graphically and analyze their domain and range.
