Understanding Intervals and Set Notation

This video tutorial by Mr. Math Fog introduces the first lesson in Integrated Math 2, focusing on domain, range, and end behavior. It explains the concepts of finite and infinite intervals, set notation, and interval notation. The tutorial includes examples and practice problems to help students understand how to determine the domain, range, and end behavior of functions. Additionally, it covers the union of sets and how to represent intervals using different notations.
