Exercise 1 Page P3

If a relation is a function, how many values can any value have?

Is It a Function? Yes
Domain:
Range:

For a relation to be a function, each value can only be paired with one value, but one value can be paired with multiple values.
Examining the ordered pairs, we can see that there is no value with multiple 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 values. The range is found by listing the relation's values.
