Find the range of the relation [(1, -4), (2,5), (3,5)]. Then determine whether the relation is a function.
To find the range of a relation, we need to look at the second elements of each ordered pair. The range is the set of all second elements in the relation.
Given the relation [(1, -4), (2,5), (3,5)], the second elements are -4, 5, and 5.
Therefore, the range of the relation is {-4, 5}.
To determine whether the relation is a function, we need to check if each first element is paired with only one second element. If each first element is paired with exactly one second element, then the relation is a function.
In this case, the first element 2 is paired with the second element 5, and the first element 3 is also paired with the second element 5.
Since multiple first elements are paired with the same second element (5), the relation is not a function.
