label a point f inside the curve. why is this an inefficient point? label a point g outside the curve. why is this point unattainable? why are pointS A THROUGH E ALL EFFICIENT POINTS?

To label a point as "f" inside the curve, you need to determine the coordinates of the point. Without specific details about the curve or its equation, I cannot provide a precise answer. However, I can help you understand the concept.

Efficiency is a subjective term and can vary depending on the context. In some cases, a point "f" inside the curve might be considered inefficient because it does not lie on the curve itself. If the curve represents a boundary or a target, any point that deviates from that curve might be considered less efficient or not meeting the desired criteria.

On the other hand, to label a point as "g" outside the curve, again you would need specific information about the curve or its equation. However, if by "outside the curve" you mean a point that lies beyond the boundary or target represented by the curve, such a point would typically be considered unattainable. It means it is not within the feasible or desired range defined by the curve.

Coming to points "A" through "E," you mentioned that they are all efficient points. Efficient points are generally identified based on certain factors or criteria predefined in a given context. Without specific information about these points or the criteria being used, it is challenging to explain their efficiency.

To make an informed judgment about efficiency in a specific situation, you would typically need to consider the objective or goal, any constraints or limits involved, and the specific metrics or measures being used to evaluate efficiency.
