Answer: D.

First set is the domain.

Answer 2

Option: D is the correct answer.

The range of the function is:

{2,4,9,16}

Explanation:

We know that a range of a function is the set or collection of all the values that are attained by a function.

i.e. it is the image of the element that belong to domain.

From the Mapping diagram that is provided to us we observe that:

1 is mapped to 2.

2 is mapped to 4.

3 is mapped to 9.

4 is mapped to 16.

Hence, the range of the function is:

{2,4,9,16}
