Let A = {2, 4} and B = {1, 3, 5} and define a relation U, V and W from A to B as follows: For every (x, y) is in A ✕ B, every (x, y) is in U means that y - x = 1.
every (x, y) is in V means that x < y .
W means that x/y is an integer.
(a) Draw arrow diagrams for U, V and W
(b) Indicate whether any of the relations U, V, and W are functions.

every (x, y) is in V means that x < y .

W means that x/y is an integer.

(a) Draw arrow diagrams for U, V and W

(b) Indicate whether any of the relations U, V, and W are functions.
