Definition. A real-valued function f defined on a domain X has a global (or absolute) maximum point at x∗, if f(x∗) ≥ f(x) for all x in X. Similarly, the function has a global (or absolute) minimum point at x∗, if f(x∗) ≤ f(x) for all x in X.
Ist f’< 0 links von x s und f’ > 0 rechts von xs , dann handelt es sich um einen Tiefpunkt. Ist f’ > 0 links von x s und f’ < 0 rechts von x s , dann betrachtest du einen Hochpunkt. Schau dir dazu gleich mal ein Beispiel an: Bestimme die Hochpunkte und Tiefpunkte von f: f (x) = x 2.
A high point is called a maximum (plural maxima). A low point is called a minimum (plural minima). The general word for maximum or minimum is extremum (plural extrema). We say local maximum (or minimum) when there may be higher (or lower) points elsewhere but not nearby.
Global (or Absolute) Maximum and Minimum. The maximum or minimum over the entire function is called an "Absolute" or "Global" maximum or minimum. Assuming this function continues downwards to left or right: The Global Maximum is about 3.7; There is no Global Minimum (as the function extends infinitely downwards) Calculus

Finding the maximum and minimum values of a function has practical significance because we can use this method to solve optimization problems, such as maximizing profit, minimizing the amount …
The extreme value theorem states that a continuous function over a closed, bounded interval has an absolute maximum and an absolute minimum. As shown in Figure 4.13 , one or both of these absolute extrema could occur at an endpoint.
