WebMore formally, a relation is defined as a subset of A × B. The domain of a relation is the set of elements in A that appear in the first coordinates of some ordered pairs, and the image or range is the set of elements in B that appear in the second coordinates of some ordered pairs. For brevity and for clarity, we often write xRy if (x, y) ∈ R. WebDecide whether the relation defined by the graph to the right defines a function, 10- 8 6 and give the domain and range.
