List the domain and range of the relation {(6,8), (7,7), (0,-8), (7,1), (6,8)}

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.
