विकल्प

• {1, 2, 3}

• {1, 2}

• {1, 3}

• None of these

Answer 1

Let A = {1, 2, 3} then the domain of the relation R = {(1, 1), (2, 3), (2, 1)} defined on A is {1, 2}.

Explanation:

Because the ordered pair's x-coordinate represents the domain (x, y). As a result, the supplied relation's domain is {1, 2}.
