Answer 1

Let C = (0, 1, 2) and D = (2, 4, 6, 8) and define a relation R from A to B as follows: For all (x , y) Ꞓ A x B, (x, y) Ꞓ R means that is an integer. a. Is 1 R 2? Is 2 R 8? Is (1, 8) Ꞓ R? Is (2, 6) Ꞓ R? b. Write R as a set of ordered pairs. c. Write the domain and co – domain of R. d. Draw an arrow diagram for R.
