If A = {a, b, c, d}, then a relation R = {(a, b), (b, a), (a, a)} on A is

If R is a relation on the set A = {1, 2, 3, 4, 5, 6, 7, 8, 9} given by x R y ⬄ y = 3x, then R =

If R is a relation on the set A = {1, 2, 3} given by R = (1, 1), (2, 2), (3, 3), then R is

If A = {1, 2, 3}, then a relation R = {(2, 3)} on A is

Let R be the relation on the set A = {1, 2, 3, 4} given by

R = {(1, 2), (2, 2), (1, 1), (4, 4), (1, 3), (3, 3), (3, 2)}. Then,
