Learn the basics of how to determine the domain and range of a function

The video tutorial explains the concepts of domain and range using examples of coordinate points and graphs. It highlights the difference between listing points and understanding graphs, emphasizing that graphs represent infinite points. The tutorial guides viewers through identifying domain and range by analyzing which values are included or excluded, and concludes with a summary of these concepts.
