The range depends on the domain. You usually define the domain (the values that x can take) first. Then the range (or codomain) is the set of all values that y can take, as defined by the functional relationship.

So, for example, if x could only take the value 5, then the range would be the single value, 12.

If x could take any value from 5 to 6, the range would be 12 to 13.

If x can take any positive value, then the range is any number greater than or equal to 7.

And so on.
