We have, it's defined for a certain-- if this was a whole relationship, then the entire domain is just the numbers 1, 2-- actually just the numbers 1 and 2.
And then you have a set of numbers that you can view as the output of the relation, or what the numbers that can be associated with anything in domain, and we call that the range. We could say that we have the number 3. You could have a negative 2. Hope that helps:-)(34 votes). It's really just an association, sometimes called a mapping between members of the domain and particular members of the range. If there is more than one output for x, it is not a function.
