Answer:
The given relation is not a function.
Step-by-step explanation:
The following relation: {(6, -1), (-4, 2), (5, 2), (4, 6), (6, 5)} is not a function because the ordered pairs (6, -1) and (6, 5) have the same domain.
By definition:
- A function is a relation in which no two ordered pairs have the same first component (x-coordinates) and different second components (y-coordinates).
- A function can only take on one output (y-value) for each input (x-value).
These are the reasons why the given relation is not a function.
