Question

What is the domain of the relation? {(-5, -4), (-2,-1), (1,0), (2,2), (4,3)}

Answer 1

The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.
