Exercise 2 Page P5

For a relation to be a function, each x-value can only be paired with one y-value, but one y-value can be paired with multiple x-values. (-6, 0), (5, 5), (9, -2), (-2, -9) Examining the ordered pairs, we can see that there is no x-value with multiple y-values. Therefore, the relation is a function. Now let's look for the domain and range of the given coordinate pairs. The domain of a function is found by listing the relation's x-values. The range is found by listing the relation's y-values. Domain:& { -6, -2, 5, 9} Range:& { -9, -2, 0, 5}
