Learn how to determine the domain and range from a function

The video tutorial explains the concepts of domain and range in graphs. It begins by introducing the domain as the set of all X values in a graph and discusses how there are infinite points within the domain. The tutorial emphasizes that the domain extends to both negative and positive infinity. It then shifts focus to the range, which is the set of all Y values, and explains that the range can also extend to infinity but may have an upper limit. The video concludes with an exercise for students to determine the domain and range of given graphs.
