WebTo prove the Mean Value Theorem using Rolle's theorem, we must construct a function that has equal values at both endpoints. The 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 ...
