Question

Identify the domain and range of the relation.. . {(-9, 2), (-4, 2), (3, 2), (9, 2)}

Answer 1

The domain of this relation is D = {-9,-4,3,9} and the range of this relation is R = {2}. The domain is all the possible x values of a relation while the range is all the possible y values. I hope this answers your question.

Answer 2

Answer:  The domain and range of the given relation are

Domain = {-9, -4, 3, 9}  and  Range = {2}.

Step-by-step explanation:  We are given to identify the domain and range of the following relation :

R =  {(-9, 2), (-4, 2), (3, 2), (9, 2)}.

We know that

if a relation is written in form of ordered pairs, then

the set of first elements form the domain of the relation and the set of second elements form the range of the relation.

Therefore, for the given relation, we get

Domain = {-9, -4, 3, 9}

and

Range = {2}, since the second element is same in all the four ordered pairs.

Thus, the domain and range of the given relation are

Domain = {-9, -4, 3, 9}  and  Range = {2}.
