Key Concepts

Critical Numbers

Critical numbers of a function are points in the interior of the domain where the derivative is either zero or does not exist, while the function itself is defined at that point. These points are significant because they are potential locations for local extrema and, when evaluated along with the interval’s endpoints, can help in determining the absolute maximum and minimum values.

Procedure for Finding Absolute Extrema

The method for finding absolute extrema on a closed, bounded interval involves several steps: first, compute the derivative of the function and identify the critical numbers by setting the derivative equal to zero or noting where it is undefined. Next, ensure that these critical numbers lie within the interval of interest. Then, evaluate the function at these critical points and also at the endpoints of the interval. Finally, compare all these values to determine the absolute maximum and minimum of the function.

Continuous Function on a Closed, Bounded Interval

A continuous function defined on a closed, bounded interval is one that does not have any breaks or discontinuities in that interval and includes all its boundary points. This condition is crucial because it guarantees, by the Extreme Value Theorem, that the function will attain both an absolute maximum and an absolute minimum on that interval.

Extreme Value Theorem

The Extreme Value Theorem states that if a function is continuous over a closed and bounded interval, then there exist points within the interval where the function reaches its highest (absolute maximum) and lowest (absolute minimum) values. This theorem provides the theoretical foundation for searching for absolute extrema on such intervals.
