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}.
