Question

Let A = {1, 2, 3, 4, 5} and let R1, R2 be relations such that R1 ⊆ A × A, R2 ⊆ A × A. Let R1 = {(1, 1), (1, 2), (1, 5), (2, 2), (2, 4), (3, 3), (3, 4), (4, 2), (4, 4), (5, 1)} R2 = {(1, 4), (1, 5), (2, 4), (4, 1), (4, 2), (5, 5)} (a) For each of the following operations on R1 and R2, determine if the result is reflexive, symmetric, and transitive. If it does not have a property, provide a specific example that shows why not. (i) R1 ∩ R2 (ii) R1 ∪ R2 (iii) R1 − R2 (b) Calculate the composition R1 ◦ R2.
