WebRolle’s Theorem. Let f be a continuous function over the closed interval [a, b] and differentiable over the open interval (a, b) such that f(a) = f(b). There then exists at least one c ∈ (a, b) such that f′ (c) = 0. Proof. Let k = f(a) = f(b). We consider three cases: f(x) = k for all x ∈ (a, b). WebThe Mean Value Theorem states that if a function f is continuous on the closed interval [a,b] and differentiable on the open interval (a,b), then there exists a point c in the interval (a,b) such that f' (c) is equal to the function's average rate of change over [a,b]. In other words, the graph has a tangent somewhere in (a,b) that is parallel ...
