5. Let A = {2, 3, 5} and B = {6, 8, 10} and define a relation R from A to B as follows: for all (x, y) A B, (x, y) R if and only if y/x is an integer (the meaning of "if and only if" is that: if y/x is an integer, then (x, y) R; conversely, if y/x is not an integer, then (x, y) / R. So the R relation contains and only contains (x, y) A B and y/x is an integer.) (a) Write R as a set of ordered pairs. (b) Write the domain and co-domain of R. (c) Draw an arrow diagram for R
