Domain is a set of real numbers which is independent

and

Range is a set of real numbers which is dependent with the domain.

From the given problem, We have two factors, the age of a person

and the number of book read.

We can say that the numbers of books read is dependent on the age of a person.

So the domain would be the age

and the range will be the number of books read.

From the table :

Age : 65, 36, 29, 29

Books Read : 42, 37, 37, 17

Remember that in listing the domain and range, there must be NO duplicates

So the domain is : 29, 36, 65

and

the range is : 17, 37, 42

The correct answer is Choice D.
