Final answer:
The given relation is also a function. The domain is {8, 7, 4, 2, 6, 1} and the range is {-2, 0, 5, 2, 6}.
Step-by-step explanation:
The given relation {(8,-2),(7,0),(4,5),(2,2),(6,5),(1,6)} is also a function. A relation is considered a function if each input value (x-coordinate) has a unique output value (y-coordinate). In this case, each x-value appears only once in the relation, so it satisfies the definition of a function.
The domain of the function is the set of all x-values in the relation. In this case, the domain is {8, 7, 4, 2, 6, 1}.
The range of the function is the set of all y-values in the relation. In this case, the range is {-2, 0, 5, 2, 6}.
