Domain In a set of ordered pairs, (x, y), the
domain is the set of all x-coordinates.
Range In a set of ordered pairs, (x, y), the
range is the set of all y-coordinates.

The set of ordered pairs may be a limited number
of points. Given the following set of ordered
pairs, find the domain and range.
Ex(2,3),(-1,0),(2,-5),(0,-3)
If a number occurs more than once, you do not
need to list it more than one time.
4
