One of the applications of derivatives is to use critical points to identify extrema.  This is often related to finding maximum or minimum values in applications.  While you should determine whether the extrema found is a maximum or minimum, sometimes it is not strictly necessary because in the context of the problem, the type of extrema identified by your critical point is obvious.
