Let R be a relation on the set of all integers such that aRb if and only if 3a – 5b is ev 1) Is R reflexive? If yes, justify your answer; if no, give a counterexample. 2) Is R symmetric? If yes, justify your answer; if no, give a counterexample. Hint: 3b – 5a = 3a – 5b + 8b – 8a 3) Is R anti-symmetric? If yes, justify your answer; if no, give a counterexample.
