Let A = {1, 2}, B = {3, 4,5}, and (x, y) E A x B, and answer the following questions: A. Use the set-roster notation to write set A X B. B. Define a relation R from A to B such that (x, y) E R means that x is an even integer and y is an odd integer. Use the set-roster notation to write R. What are the domain and co-domain? C. Is {(1, 5), (2, 4), (1, 3); a function from A to B? D. Is { (1, 4), (2, 4), (1, 4); a function from A to B? E. Is { (3, 1), (5, 2), (4, 2); a function from B to A
