what is the domain and range of {(-2,-1) (-1,0), (0,-1), (2,-1)} ?

The domain is the set of the first coordinates of these points:  {-2, -1, 0, 2}.  They are listed here in the same order.

The range is the set of the second coordinates of these points:  {-1, 0, -1, -1}.  They are listed in the same order.
