![]() ![]() Thus, we simply evaluate the function at each endpoint and each critical number in the interval, and compare the results to decide which is largest (the absolute maximum) and which is smallest (the absolute minimum). If we are working to find absolute extremes on a restricted interval, then we first identify all critical numbers of the function that lie in the interval.įor a continuous function on a closed, bounded interval, the only possible points at which absolute extreme values occur are the critical numbers and the endpoints. ![]() In the case of finding global extremes over the function's entire domain, we again use a first or second derivative sign chart. If instead we are interested in absolute extreme values, we first decide whether we are considering the entire domain of the function or a particular interval. To find relative extreme values of a function, we use a first derivative sign chart and classify all of the function's critical numbers. Given a differentiable function \(f\text\) then the second derivative does not tell us whether \(f\) has a local extreme at \(p\) or not. These values are important because they identify horizontal tangent lines or corner points on the graph, which are the only possible locations at which a local maximum or local minimum can occur. The critical numbers of a continuous function \(f\) are the values of \(p\) for which \(f'(p) = 0\) or \(f'(p)\) does not exist. know the basic rules of differentiation and use them to find derivatives of products and quotients, know the chain rule and use it to find derivatives of.
