Correct Answer - Option 1 : A = {0, 1, 2, 3, 4, 5} and B = {5, 6, 7, 8, 9, 10}
Concept:
Domain of a Relation: Let R be a relation from set A to set B. Then, the set of all first components of the ordered pair belonging to relation R forms the domain of the relation R i.e Domain (R) = {a: (a, b) ∈ R}.
Range of a Relation: Let R be a relation from set A to set B. Then, the set of all second components of the ordered pair belonging to relation R forms the range of the relation R i.e Range (R) = {b: (a, b) ∈ R}.
Calculation:
Given: A and B are the domain and range respectively for the relation R such that R = {(x, x + 5) : x ∈ {0, 1, 2, 3, 4, 5}}
So, the relation R can be re-written as: R = {(0, 5), (1, 6), (2, 7), (3, 8), (4, 9), (5, 10)}
As we know that, Domain (R) = {a: (a, b) ∈ R}.
⇒ A = {0, 1, 2, 3, 4, 5}
We also know that, Range (R) = {b: (a, b) ∈ R}.
⇒ B = {5, 6, 7, 8, 9, 10}
Hence, option 1 is the correct answer.
