Describing Relations and Functions: Analyzing Visual and Verbal Representations

This video tutorial explains how to describe relations and functions using visual and verbal representations. It covers the concepts of domain and range, and how to use mappings, T charts, and graphs to illustrate relations. The video also defines functions as a special type of relation where each domain element is paired with exactly one range element. Examples are provided to clarify the distinction between relations and functions, and methods to identify functions in different formats are discussed.
