f=(2,5),(3,7),(4,6)

Given:

Here given that

            A= \left \{ 2,3,4 \right \}   and   A= \left \{ 2,5,6,7 \right \}

Here we have to construct an example of injective.

Hint:

For injective, we have to construct the example of one-one function.

Solution:

Here      A= \left \{ 2,3,4 \right \}   and   A= \left \{ 2,5,6,7 \right \}

Hence for injective (i.e) one-one.

            f=(2,5),(3,7),(4,6)

Hence the result.
