Question

If A = {1, 2, 3}, B = {1, 4, 6, 9} and R is a relation from A to B defined by x is greater than y. The range of R is

• A. {1, 4, 6, 9}
• B. {4, 6, 9}
• C. {1}
• D. None of these

Answer 1

The correct option is C

{1}

A = {1, 2, 3} and B = {1, 4, 6, 9}

R is a relation from A to B defined by : x is greater than y.

Then R = {(2, 1), (3, 1)}

$\therefore$ Range (R) = {1}
