Question

What is the domain and the range of the relation represented by the ordered pairs?

{(6,3),(−2,3),(3,6),(0,4)}
Select each correct answer.


A) range: {−2,0,3,6}

B) domain: {−2,0,3,6}

C) domain: {3,4,6}

D) range: {3,4,6}

Answer 1

The domain is the set of the x values in the ordered pairs and the range is the set of y values ( without duplicates)

Here the Domain is {-2 0 3 6}

Range = {3, 4 6}

Answer 2

B) domain: {−2,0,3,6}

D) range: {3,4,6}

Explanation:

The given relation represented by ordered pairs are;

{(6,3),(−2,3),(3,6),(0,4)}

The domain refers to the set of all the first coordinates, which are the x-coordinates.

The domain is {
`-2,0,3,6`}

The range refers to the set of all the second coordinates, which are the y-coordinates.

The range {
`3,4,6`}.

Note that, 3 appears twice but, we list it only once.

The correct answers are B and D.
