Since a relation is a set, we can describe a relation by listing its elements (that is, using the roster method). let a = {1, 2, 3, 4, 5, 6} and b = {1, 2, 3, 4}. define (a, b) ∈ r if and only if (a − b) mod 2 = 0. then. r = {(1, 1), (1, 3), (2, 2), (2, 4), (3, 1), (3, 3), (4, 2), (4, 4), (5, 1), (5, 3), (6, 2), (6, 4)}.

Let r be the relation on the set of functions from z to z such that (f, g) ∈ r if and only if f is Θ(g). show that r is an equivalence relation. proof: we need to show that r is reflexive, symmetric, and transitive. reflexive: since 1 · f(x) ≤ f(x) ≤ 1 · f(x) for all x ≥ 1, f = Θ(f), so r is reflexive. Let r be a relation from a set a to a set b and s a relation from b to a set c. the composite of r and s is the relation consisting of the ordered pairs (a,c) where a a and c. s. we denote the composite of r and s by s o r. let a = {1,2,3}, b = {0,1,2} and c = {a,b}. s o r = ? relation from b to a set c.
