Activity 1. A Relation as a Subset Let A = {1,2} and B = (x, y) E Ax B, {1,2,3} and define a relation R from A to B as follows: Given any (x, y) ER means that is an integer x-y A. State explicitly which ordered pairs are in A X B and which are in R. B. Is 1 R 3? Is 2 R 3? Is 2 R 2? What are the domain and co-domain of B2
