Exercise 5 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. In a mapping, the x-values in the domain can only point to one y-value in the range.

In the given mapping, we can see that none of the x-values correspond to multiple y-values. Since all of the values in the domain only point to one value in the range, the relation is a function. Now we can list the elements in the domain and range. Domain:& {-2, -1, 0, 3} Range:& {-3, -2, 2}
