7.2: Proof of the Intermediate Value Theorem

WebBolzano's Theorem The statement of Bolzano's Theorem is: Suppose f(x) is continuous on the closed interval [a, b], and suppose that f(a) and f(b) have opposite signs. Then there exists a number c in the interval [a, b], for which f(c) = 0. Proof. Proof of the Intermediate Value Theorem Bolzano used the following formulation of the theorem: [6] Let be continuous functions on the interval between and such that and . Then there is an between and such that . The equivalence between this formulation and the modern one can be shown by setting to the appropriate constant function. See more In mathematical analysis, the intermediate value theorem states that if $${\displaystyle f}$$ is a continuous function whose domain contains the interval [a, b], then it takes on any given value between $${\displaystyle f(a)}$$ See more A form of the theorem was postulated as early as the 5th century BCE, in the work of Bryson of Heraclea on squaring the circle.
