Graphing Piecewise Functions With Three Equations

The video tutorial covers graphing functions, focusing on linear and piecewise functions. It explains how to rewrite equations in the form y=mx+b for easier graphing and discusses the importance of constraints in graphing. The tutorial also covers the vertical line test to determine if a graph represents a function and explains the concepts of domain and range, emphasizing the importance of understanding these concepts for accurate graphing.

What happens to the graph if a function does not pass the vertical line test?

What is the domain of the graph discussed in the video?

How does the range of a function differ from its domain?
