Let \(A =\{5,6,9,13\}\) and \(B = \{2,9,14\}\). Which of the following sets are relations from \(A\) to \(B\)?
(i) \(R_1 = \{(5,9), (6,9), (9,14), (13,2)\}\)
Answer: \(R_1\) of \(A \times B\), thus it is .
(ii) \(R_2 = \{(5,2), (6,12)\}\)
Answer: \(R_2\) of \(A \times B\), thus it is
(iii) \(R_3 = \{(5,9), (6,14), (9,9), (9,13), (13,11), (13,9), (13,14)\}\)
Answer: \(R_3\) of \(A \times B\), thus it is
