WebThe Extreme value theorem states that if a function is continuous on a closed interval [a,b], then the function must have a maximum and a minimum on the interval. This makes sense: when a function is continuous you can draw its graph without lifting the pencil, so you must hit a high point and a low point on that interval. Created by Sal Khan. WebCompare the f(x) values found for each value of x in order to determine the absolute maximum and minimum over the given interval. The maximum will occur at the highest …

WebGlobal (or Absolute) Maximum and Minimum The maximum or minimum over the entire function is called an "Absolute" or "Global" maximum or minimum. There is only one global … WebHowever, since x2 + 1 ≥ 1 for all real numbers x and x2 + 1 = 1 when x = 0, the function has a smallest value, 1, when x = 0. We say that 1 is the absolute minimum of f(x) = x2 + 1 and it occurs at x = 0. We say that f(x) = x2 + 1 does not have an absolute maximum (see the following figure). open source software security issues
