For this case we have:
By definition, a mathematical function is the correspondence or relation f of the elements of a set A with the elements of a set B. A function fulfills the condition of existence (all the elements of A are related to the elements of B) and with the condition of uniqueness (Each element of A is related to a single element of B).
That said, we can conclude that the relationship shown in the table defines a function of the form
By definition, the domain of a function is represented by the input elements of it.
Thus, the domain is given by Domain: (m, n, p, q)
Answer:
Yes, Domain: (m, n, p, q)
Option A
