Domain and Range Concepts

This video tutorial by Houston Math Prep introduces the concepts of domain and range in mathematics, focusing on their definitions and how they relate to functions and relations. The video explains how to identify the domain and range from a set of ordered pairs and provides examples using month numbers and days. It also demonstrates how to list domain and range values from a table, emphasizing the importance of listing unique values only. The tutorial concludes with a practical example to reinforce the concepts discussed.

What is the primary focus when considering a relation in mathematics?

• The domain and range

• The order of elements

• The color of elements
