Answer: Choice C

Domain: {-1, 1, 4}

Range: {-4, 3, 4}

Not a function

========================================================

Step-by-step explanation:

The domain is the set of allowed x inputs, while the range is the set of allowed y outputs.

To form the domain, we simply list the x coordinates of each point. Toss any duplicates. The range is the same story, but with the y coordinates.

We do not have a function because x = 4 repeats itself. The input x = 4 leads to multiple outputs.

Side note: it's optional to sort each set.
