Explanation:
the x-coordinates and y-coordinates, respectively, of each point in the set.
Domain:
The domain is the set of all possible x-coordinates in the set of points. In this case, the x-coordinates are -2, -1, 0, 1, and 2. So the domain of R is:
Domain = {-2, -1, 0, 1, 2}
Range:
The range is the set of all possible y-coordinates in the set of points. In this case, the y-coordinates are -7, -2, 1, and 2. So the range of R is:
Range = {-7, -2, 1, 2}
Therefore, the domain of R is {-2, -1, 0, 1, 2}, and the range of R is {-7, -2, 1, 2}.
