Identify the domain and range of each relation. Use a mapping diagram to determine whether the relation is a function.
{(9, 6), (3, 8), (4, 9.5), (9, 2)}
The domain of the relation is {9, 3, 4} and the range is {6, 8, 9.5, 2}.
To determine if the relation is a function, we can use a mapping diagram.
Mapping Diagram:
9 -> 6
3 -> 8
4 -> 9.5
9 -> 2
Since there is only one arrow pointing to each element of the domain, this relation is a function.
