The range of a relation in mathematics refers to the set of all second elements (y-values) in the ordered pairs of the relation. For the given relation {(2, 4), (3, 4), (4,7), (5,7), (6,5)}, the second elements are 4, 4, 7, 7, and 5.
To find the range, we list these numbers but we need to remove any duplicates because in sets, each element is unique. So after removing duplicates, the range of the given relation is {4, 7, 5}.
