For each of these relations on the set {1, 2, 3, 4}, decide whether it is reflexive, whether it is symmetric, whether it is antisymmetric, and whether it is transitive. a) {(2,2),(2,3),(2,4),(3,2),(3,3),(3,4 )} 7. is reflexive, symmetric, antisymmetric, and/or transitive, where (x, y) ∈ R if and only if {(1, 1), (1, 2), (2, 1), (2, 2), (3, 3), (4, 4)} {(2, 4), (4, 2)} {(1, 2), (2, 3), (3, 4)} {(1, 1), (2, 2), (3, 3), (4, 4)} b) c) d) e)
