Answers:
Domain = {0, 6, 7}
Range = {-8, 1, 7, 8}
======================================================
Explanation:
The domain is the set of allowed x inputs. So we simply list the x coordinates. Toss out any duplicates. Sorting the values is optional.
The range is the set of y coordinates. Like with the domain, we'll toss out any duplicates and optionally we can sort the y values.
