Date: Question 1: Use the Intermediate Value Theorem (IVT) to determine an interval for which the function f (x)--e has an x-intercept. Next, use Newton's Method to approximate the zero in the interval. Con- tinue the iterations until two successive approximations differ by less than 0.001 Solution: First apply IVT Use the Newton's method formula and then use the chart below in order to keep organized f(n) f(n) Tn Tn 4 Date: Question 1: Use the Intermediate Value Theorem (IVT)...
2. Rolle's theorem states that if F : [a, b] → R is a continuous function, differentiable on Ja, bl, and F(a) = F(b) then there exists a cela, b[ such that F"(c) = 0. (a) Suppose g : [a, b] → R is a continuous function, differentiable on ja, bl, with the property that (c) +0 for all cela, b[. Using Rolle's theorem, show that g(a) + g(b). [6 Marks] (b) Now, with g still as in part (a),...

Let s < t and let f:[s,t]→ℝ be a differentiable function. Suppose that f'(x) > 0 for all x Which of the following is correct? 1. Using the definition of the derivative, it follows that f(x)<f(a) for any x<a. 2. Using Rolle's Theorem, it follows that f is a continuous function. 3. Using the Mean Value Theorem, it follows that f(t)>f(s). 4. Using Rolle's Theorem, it follows that there is some x∈[s,t] such that f′(x)=0. 5. Using the Intermediate Value...
