Understanding Interval Notation and Range

The video tutorial covers the concepts of domain and range in mathematics, focusing on how to determine these for different types of graphs. It explains the use of interval notation to express domain and range, highlighting the difference between using parentheses and brackets. The tutorial analyzes four different graphs: a linear graph, a parabolic graph, a graph with restrictions, and a graph with asymptotes, providing detailed explanations for each. The video aims to make the concepts of domain and range more accessible and understandable through practical examples.
