The domain of a set of ordered pairs is the set of all first elements from each pair, and the range is the set of all second elements. For the given set {(-2,9),(8,-2),(-4,-6),(10,-1)}, the domain is {-4,-2,10,8} and the range is {-6,9,-1,-2}. Each element in the domain and range is unique and listed without repetition.
