WEBThe domain and range of a relation are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = { (1, 2), (2, 2), (3, 3), (4, 3)}, then: Domain = the set of all x-coordinates = {1, 2, 3, 4} Range = the set of all y-coordinates = {2, 3}
