Answer:
See attachment
The relation is not a function.
The domain is [-4.1,3.9]
The range is [-2.1,5.9]
Explanation:
The given relation has ordered pairs (3.9, 5.9), (–1.1, 5.9), (–4.1, 3.9), (–4.1, –2.1)
It is implied in the ordered pairs that the relation is a continuous function.
We plot the points and connect them with straight lines as shown in the attachment.
The relation is not a function because its graph fails the vertical line test.
In other words, we have an x-coordinate that corresponds to more than one y-coordinate.
-4.1 corresponding to 3.9 and -2.1 at the same time.
The domain is the set of values for which the function is defined.
The domain is [-4.1,3.9]
The range refers to the corresponding y-values for which the function exists.
The range is [-2.1,5.9]
