Question

3. Is the relation a function?(14, 15), (5,7), (3, 10), (11, 1), (5.8)a-yesb-no

Answer 1

The given relation is

(14, 15), (5,7), (3, 10), (11, 1), (5.8)

Here consider the pair (5,7) and (5,8)

Input 5 gives two outputs 7 and 8

But function has exactly one output for one input.

Hence this relation is not a function.
