If A={1,2,3,4},B={1,5,9,11,15,16} and `f={(1,5),(2,9),(3,1),(4,5),(2,11)}` are the following statements true ?
(i) f is a relation from A to B .
(ii) f is a function from A to B
Justify your answer.

Text Solution

Verified by Experts

The correct Answer is:
N/a
`(i)becausesubeAxxB`
`therefore` It is not a function from A to B because the first componnents of (2,9) and (2,11) are same.
