Final answer:
No, evaluating a function outside of its feasible region is not always possible and it depends on the function itself. There are cases where a function can be evaluated outside of its feasible region if there is an extension of the function that allows for it.
Step-by-step explanation:
The answer to the question is B. No, and they are not mutually exclusive either. Evaluating a function outside of its feasible region is not always possible and it depends on the function itself. It is possible for a function to be evaluated outside of its feasible region if there is an extension of the function that allows for it.
