Choose the relation with a domain of {-6, -3, -2, 0, 5}.
Answer
R = {(-3, 5), (-6, 4), (-2, 2), (5, -2) (0, -1)}
R = {(-6, -3), (-2, -2), (0, 5)}
R = {(6, 5), (3, 0), (5, -3), (5, -6), (8, -2)}
R = {(5, 0), (-2, -2), (-3, -6)}
Please and thank you for your help. (: I really do need help on this so thank you to those who are willing to help me.
