Final answer:
The domain of the relation Q is {-2, 0, -1, 4}, and the range is {4, 2, 3, -2}.
Step-by-step explanation:
The domain of a relation is the set of all first elements of the ordered pairs, and the range is the set of all second elements of the ordered pairs.
For the given relation Q = { (-2, 4), (0, 2), (-1, 3), (4, -2)}, the domain is the set of all x-coordinates from the ordered pairs, which are {-2, 0, -1, 4}. The range, similarly, is the set of all y-coordinates from the ordered pairs, which are {4, 2, 3, -2}.
