Example 7 Let A = {1, 2, 3, 4, 5, 6}. Define a relation R from A to A by R = {(x, y) : y = x + 1 } Depict this relation using an arrow diagram. It is given that y = x + 1 Also, x, y ∈ A R = {(1,2), (2,3), (3,4), (4,5), (5,6)}. Arrow Diagram R from A to A A = {1, 2, 3, 4, 5, 6} Example 7 Let A = {1, 2, 3, 4, 5, 6}. Define a relation R from A to A by R = {(x, y) : y = x + 1 } (ii) Write down domain, co-domain and range of R R = {(1,2), (2,3), (3,4), (4,5), (5,6)}. Domain = Set of all first elements in relation = { 1,2,3,4,5} Range = Set of all second elements in relation = { 2,3,4,5,6} Co-domain = Set A (the whole right set in this relation) = { 1,2,3,4,5,6}
