WebThe Mean Value Theorem states the following: suppose ƒ is a function continuous on a closed interval [a, b] and that the derivative ƒ' exists on (a, b). Then there exists a c in (a, b) for which ƒ (b) - ƒ (a) = ƒ' (c) (b - a). Proof Construct a new function ß according to the following formula: ß (x) = [b - a]ƒ (x) - x [ƒ (b) - ƒ (a)]. An open interval does not include its endpoints, and is indicated with parentheses. For example, (0, 1) means greater than 0 and less than 1. This means (0, 1) = {x 0 < x < 1}. This interval can also be denoted by ]0, 1[, see below. A closed interval is an interval which includes all its limit points, and is denoted with … See more In mathematics, a (real) interval is a set of real numbers that contains all real numbers lying between any two numbers of the set. For example, the set of numbers x satisfying 0 ≤ x ≤ 1 is an interval which contains 0, 1, and … See more The interval of numbers between a and b, including a and b, is often denoted [a, b]. The two numbers are called the endpoints of the interval.
