Determine the domain and the range of the relation, and tell whether the relation is a function.
{(9,2). (21, - 5), (39,2), (9,9), (58,9)}
The domain is the set of all x-values in the relation. In this case, the domain is {9, 21, 39, 58}.
The range is the set of all y-values in the relation. In this case, the range is {2, -5, 9}.
To determine if the relation is a function, we need to check if each x-value is paired with exactly one y-value. Here, we can see that the value of 9 is paired with both 2 and 9. Therefore, the relation is not a function.
