Recall, a rule assigning elements of a set A to a set B is said to be well-defined if the assignment of elements in A to those of B is unique. Furthermore, such a rule is said to be a function when it is well-defined. Consider the rule f:Q → Z m where f = m -n for any q = E Q. Explain why this rule is not a function.
