What does an Ordered Pair mean?

Generally, it (x,y) as laid out on an x-y coordinate system.  The collection of all first values, all the x's, is the Domain.

Look at all your ordered pairs and pick out all the unique x-values (the first value in each ordered pair).  This will give you the domain.  Go!
