Relations and Functions

By the end of this section I can:

• define relation, domain, and range
• find domain and range given a relation as a table, mapping, or set of ordered pairs
• represent relations as graphs, mappings, tables, equations, or sets of ordered pairs
• determine if relations are functions
• apply the vertical line test to determine if a relation is a function
