3-1 Relations and Functions – We learned that a relation is an association between sets of ordered pairs where the domain consists of the set of x-values and the range consists of the set of y-values. Then we learned to identify functions and their components in a variety of forms such as graphs, tables, and ordered pairs. Next we learned that a relation is a function only if each element of the domain is assigned to exactly one element in the range. Finally we identified constraints on the domain based on real-world problems.
