Question
Let R be the relation in the set N given by R = {(a, b) : a = b – 2, b > 6}, then ______.
Options
(2, 4) ∈ R
(3, 8) ∈ R
(6, 8) ∈ R
(8, 7) ∈ R
Solution
Let R be the relation in the set N given by R = {(a, b) : a = b – 2, b > 6}, then (6, 8) ∈ R.
Explanation:
a = b − 2 and b > 6
⇒ (6, 8) ∈ R
