This Algebra video tutorial provides a basic introduction into relations and functions. It explains how to write the domain and range of a relation and how to determine if the relation is a function. It also explains how to draw a mapping diagram of the relation as well as a function table. Finally, this video explains how to use the vertical line test to determine if the relation represented by a graph is a function.
