Websolution to question 1. a) f (0) = 1 and f (2π) = 1 therefore f (0) = f (2π) f is continuous on [0 , 2π] Function f is differentiable in (0 , 2π) Function f satisfies all conditions of Rolle's theorem. b) function g has a V-shaped graph with vertex at x = 2 and is therefore not differentiable at x = 2. WebFrom the definition of Rolle’s theorem, the function y = x 2 + 2 is continuous in [– 2, 2] and differentiable in (– 2, 2). From the given, f(x) = x 2 + 2

WebOct 24, 2024 · Rolle's theorem is based on the ideas of the mean value theorem, where objects in motion eventually travel at their average velocity speed. Learn the concept behind Rolle's theorem... WebThe proof follows from Rolle’s theorem by introducing an appropriate function that satisfies the criteria of Rolle’s theorem. Consider the line connecting ( a , f ( a ) ) ( a , f ( a ) ) and ( b … WebRolle’s Theorem: Rolle’s theorem says that if the results of a differentiable function (f) are equal at the endpoint of an interval, then there must be a point c where f ’(c)=0. (Image) Example: Find all values of point c in the interval [−4,0]such that f′(c)=0.Where f(x)=x^2+2x. expedia promotion
