The domain of a relation is the set of all first elements of ordered pairs (x-values), and the range is the set of all second elements of ordered pairs (y-values). In this context, the domain is the set of years (1995, 1996, 1997, 1998, 1999), and the range is the set of numbers of new telemarketing companies (56, 112, 178, 187, 318).
