Extreme Value Theorem
if f(x) is continuous on [a,b], then f(x) has an absolute max or min on the interval
The Extreme Value Theorem states that if a function f(x) is continuous on a closed interval [a, b], then it has at least one absolute maximum and one absolute minimum value on the interval.
In simple words, the theorem says that if a function is defined and continuous on a closed interval, then the function must have a highest (maximum) value and a lowest (minimum) value somewhere in that interval.
This theorem is important because it guarantees the existence of maximum and minimum values of a function. It is useful in optimization problems, where we need to find the maximum or minimum value of a function over a given interval. This theorem ensures that such values exist and can be found using appropriate methods.
To summarize, the Extreme Value Theorem helps us identify and locate maximum and minimum values of a function, which has practical applications in a variety of fields including economics, physics, engineering, and more.
