The best explanation of domain and range with multiple examples

The video tutorial covers the concepts of domain and range in mathematical functions. It begins with an introduction to graphing functions and proceeds to explain the domain and range using linear and constant functions as examples. The tutorial also explores the domain and range of parabolic functions, emphasizing the infinite nature of these values in certain functions. The teacher uses examples and encourages students to think critically about the concepts, ensuring a comprehensive understanding of domain and range.
