The Extreme Value Theorem is a mathematical concept in calculus that states that a continuous function on a closed and bounded interval must have both a maximum and a minimum value on that interval. In other words, if you have a function f(x) that is continuous on an interval [a,b], then the function must have a maximum point, which is the highest value that the function takes on within that interval, and a minimum point, which is the lowest value that the function takes on within that interval.
To put it simply, if a function is continuous and defined over a finite range, it will have an absolute maximum and minimum value. The Extreme Value Theorem is important in understanding the behavior of functions on closed intervals and can be used in a variety of real-world applications such as optimization problems, finding the highest and lowest points in a particular region, and determining the range of solutions to certain problems.
It is important to note that the Extreme Value Theorem only applies to continuous functions on closed and bounded intervals. If a function is either discontinuous, or not defined on a closed interval or not bounded, it may not have a maximum or minimum value within that interval. In such cases, alternative techniques like the first and second derivative tests, or the use of critical points, may be used to find the maximum and minimum values of the function.
