The domain of a relation consists of all the first elements (or x-coordinates) from each ordered pair.
For the pairs given:
- (3, 3)
- (3, 5)
- (6, 0)
- (5, 5)
The first elements are: 3, 3, 6, and 5.
When listing the domain, we only include each unique value once. Therefore, the domain of the relation is:
\({3, 5, 6}\)
