(a) Is O reflexive? No v, because when m = 0 then m - m is not odd. (b) Is O symmetric? Yes v , because for any vv integers m and n, if m - n is odd then n v v - m is v v odd. (c) Is O transitive? No V V , because when m = 8, n = , and o = 0 , then m - n is v V odd, n - o is X odd, and m - o is not odd. Need Help? Read It
