Finding Absolute Maximum and Minimum Values

Web18. To determine the absolute maximum or minimum, consider the endpoints of the interval as well as the local extrema. This is because the absolute maximum or minimum may occur at the endpoints of the interval, or at a local extrema within the interval. We need to check all of these possibilities to find the absolute maximum or minimum. WebTheorem 5.54. Extreme Value Theorem. If a function f f is continuous on a closed interval [a,b], [ a, b], then f f has both an absolute maximum and an absolute minimum on [a,b]. [ a, b]. Although this theorem tells us that an absolute extremum exists, it does not tell us what it is or how to find it. pontoon food boat for sale https://rhbusinessconsulting.com
