Final answer:
The domain of the given set of ordered pairs is {1, 5, 7, 8}, and the range is {2, 6, -1, 0}.
Step-by-step explanation:
The domain of a set of ordered pairs refers to all the first elements in each pair, typically representing the independent variables in a function. In the given set {(1, 2), (5, 6), (7, -1), (8, 0)}, the domain is the set of all the x-values or first elements. So, the domain is {1, 5, 7, 8}.
The range of a set of ordered pairs refers to all the second elements in each pair, typically representing the dependent variables in a function. For the same set, the range is the set of all the y-values or second elements. Hence, the range is {2, 6, -1, 0}.
