The absolute extrema of a function are the largest and smallest values of the function. What is the most profit that a company can make? What is the least amount of fence needed to enclose a garden? Once you know how to find the absolute extrema of a function, then you can answer these kinds of questions and many more! The absolute extrema of a function f on a given domain set D are the absolute maximum and absolute minimum values of f x as x ranges throughout D. Sometimes a function may fail to have an absolute minimum or maximum on a given domain set.

To do this we will need many of the ideas that we looked at in the previous section. First, since we have a closed interval i. This is a good thing of course. Next, we saw in the previous section that absolute extrema can occur at endpoints or at relative extrema. Also, from the previous section that we know that the list of critical points is also a list of all possible relative extrema. So, the endpoints along with the list of all critical points will in fact be a list of all possible absolute extrema.

Concavity Definition of a concave up curve: f x is "concave up" at x 0 if and only if f ' x is increasing at x 0 Definition of a concave down curve: f x is "concave down" at x 0 if and only if f ' x is decreasing at x 0 The second derivative test: If f '' x exists at x 0 and is positive, then f '' x is concave up at x 0. If f '' x 0 exists and is negative, then f x is concave down at x 0. If f '' x does not exist or is zero, then the test fails. Critical Points Definition of a critical point: a critical point on f x occurs at x 0 if and only if either f ' x 0 is zero or the derivative doesn't exist. Occurrence of local extrema: All local extrema occur at critical points, but not all critical points occur at local extrema. The extreme value theorem: If f x is continuous in a closed interval I, then f x has at least one absolute maximum and one absolute minimum in I. Occurrence of absolute maxima: If f x is continuous in a closed interval I, then the absolute maximum of f x in I is the maximum value of f x on all local maxima and endpoints on I.
