Final answer:
The domain and range of the relation with the single ordered pair (1,9) are both single-element sets, with the domain being {1} and the range being {9}. More pairs would be needed to fully determine the domain and range if they consist of more elements.
Step-by-step explanation:
It appears that the given relation is incomplete as it only includes one ordered pair, (1,9). However, based on this single pair, we can identify its domain and range. The domain is the set of all first elements of the ordered pairs, which in this case is simply {1}. The range is the set of all second elements, here being {9}.
Typically, for the complete determination of the domain and range of a relation, one would consider all the ordered pairs that belong to that relation. If more pairs were provided, the domain and range would potentially include more numbers.
