We all recall from our study of calculus that we can find the maximum or minimum of a continuous function by differentiating the function and setting the first derivative equal to zero. We can determine if we are dealing with a maximum or a minimum by noting whether the second derivative is negative or positive. Of course, a function may have several maxima and/or minima. Also, a function may not be continuous.
