In functional dependencies, the values of x can take on any value from the domain of the attribute it is associated with. For example, if we have a functional dependency A -> B, where A and B are attributes in a relation, the values of A can be any value from the domain of A. This means that for each unique value of A, there is a unique value of B associated with it. **

Ultimately, the choice should be made based on what best serves the artistic vision and the audience's experience. **
