Problem 24. Suppose the function f and its derivative f' are continuous on [a,bl. Let s be the are length of the curve f from the point (a, f(a)) to (b,f(b)). 1. Let a =x0 < 시<x2 < <x,' = b be a partition ofla,bl. 2. Show that s = 1 + Lr'(x) dx by using the Mean Value Theorem for differentiation
a. Determine whether the Mean Value Theorem applies to the function f(x) = x + on the interval [3,6]. b. If so, find or approximate the point(s) that are guaranteed to exist by the Mean Value Theorem. a. Choose the correct answer below. O O A. No, because the function is not continuous on the interval [3,6], and is not differentiable on the interval (3,6). B. No, because the function is differentiable on the interval (3,6), but is not continuous...

F1. need help solving this problem. 1. (25 pts) Here's a neat theorem. Suppose that f la, b] [a, b] is continuous; then f will always map some s-value to itself (a so-called fixed point): i.e. 3 c E (a, b) for which f(c)-c (a) Give a "visual proof" of this theorem. Hint: take your inspiration from our "visual proofs" of Theorem 15 and IVT And notice here that the domain and range of f are the same interval; this...
