Find the domain and the range of the relation and determine whether it is a function.
{(7, 3),(-1, -3),(2, -2),(5, -6)}
The domain of a relation is the set of all x-coordinates of the ordered pairs in the relation. In this case, the x-coordinates are 7, -1, 2, and 5. Therefore, the domain is {7, -1, 2, 5}.
The range of a relation is the set of all y-coordinates of the ordered pairs in the relation. In this case, the y-coordinates are 3, -3, -2, and -6. Therefore, the range is {3, -3, -2, -6}.
To determine whether the relation is a function, we need to check if each x-coordinate (input) has a unique y-coordinate (output). In this case, each x-coordinate in the relation corresponds to only one y-coordinate. Therefore, the relation is a function.
