MCQ
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}
  • ✓
    {1}
  • D
    none of these.
✓

Answer

Correct option: 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}
