Answer» e the relation in the set N given by R = {(a, b): a = b − 2, b > 6}. Choose the correct answer.(A) (2, 4) ∈ R(B) (3, 8) ∈R(C) (6, 8) ∈R(D) (8, 7) ∈ RAnswerR = {(a, b): a = b − 2, b > 6}Now, since b > 6, (2, 4) ∉ RAlso, as 3 ≠ 8 − 2, (3, 8) ∉ RAnd, as 8 ≠ 7 − 2∴(8, 7) ∉ RNOW, consider (6, 8).We have 8 > 6 and ALSO, 6 = 8 − 2.∴(6, 8) ∈ RTHE correct answer is C. |
