If a relation is a function, how many y-values can any one x-value have?
Domain: {1, 2, 3}
Range: {6, 7, 10}
Yes, it is a function.
(2,7), (3,10), (1,6) 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:& {1, 2, 3} Range:& {6, 7, 10}
