Final answer:
The domain for the given set of ordered pairs is {15, 3, -1, 9}, and the range is {2, 0, -1}.
Step-by-step explanation:
The domain of a function or a set of ordered pairs is the set of all possible x values. To find the domain for the given set of ordered pairs (15,2), (3,0),(-1,-1),(9,2), we list the first element from each pair. This gives us the domain: {15, 3, -1, 9}.
The range of a function or a set of ordered pairs is the set of all possible y values. From the same set of ordered pairs, we list the second element from each pair for the range: {2, 0, -1, 2}. However, since 2 repeats, we list it only once, giving us the range: {2, 0, -1}.
