To determine if the relation presented in the mapping diagram is a function, we need to check whether each element in the domain is associated with exactly one element in the range.
A relation is considered a function if:
- Each input (or element from the domain) must correspond to one and only one output (or element from the range).
- No two different inputs can map to the same output.
Since the mapping diagram you provided does not show which elements from the domain are associated with which elements from the range, we cannot definitively conclude whether the relation is a function or not just from the list of numbers.
If you can provide the specific pairs or associations between the numbers in the domain and the numbers in the range, I would be able to help you determine if it is a function.
