Example: Sets of Ordered Pairs as a Mathematical Function
Consider the relation defined by the set of ordered pairs: {(-3, 27), (-2, 8), (-1, 1), (0, 0), (1, 1), (2, 8), (3, 27)}. We can determine if this relation is a mathematical function by examining its coordinates. Each -value is matched with only one -value, so this relation is a function. The domain is the set of all unique -values: , and the range is the set of all unique -values: {0, 1, 8, 27}.
