Well, since you asked so nicely, I'll do my best to help you out! Let's tackle the first question together.
The domain is the set of all possible x-values for the relation. In this case, the domain is (-4, -1, 1, 4).
The range, on the other hand, is the set of all possible y-values for the relation. Unfortunately, you haven't provided any information about the y-values, so we can't determine the range.
As for whether the relation is functional, a relation is considered functional if each x-value corresponds to only one y-value. Since you haven't given any y-values, we can't determine whether it is functional or not.
I hope that helps! Let me know if you have any more questions or if you want me to help with the rest of the test.
