The domain is the set of first value, the range is the set of second value.

Explanation:

For the set of ordered pairs {(2,5), (5,2),(-2,2)},

The Domain is: {2,5,-2}
(Which may also be written: {-2,2,5} if you want to put the numbers in order.)

The range is: {5,2}
(This is the same as {5,2,2}.

A set is completely determined by what is in it, regardless of the order or number of times it is written down.
