3. In this problem we shall investigate the intermediate value theorem for derivatives. (a) Differentiate the function f(c)= sin ), 2 0 = 0,1=0 Show that f'(0) exists but that f' is not continuous at 0. Roughly sketch f' to see that nevertheless, f' doesn't seem to "skip any val- ues". Now let f be any function differentiable on (a, b) and let 21,22 € (a, b). Suppose f'(21) < 0 and f'(22) > 0. (b) By the Extreme Value...

Use the Intermediate Value Theorem to verify that the following equation has three solutions on the interval (0,1). Use a graphing utility to find the approximate roots. 98x3 - 91x² + 25x -2=0 Let f be the function such that f(x)= 98x3 -91x2 + 25x – 2. Does the Intermediate Value Theorem verify that f(x) = 0 has a solution on the interval (0,1)? O A. No, the theorem doesn't apply because the function is not continuous. OB. Yes, the...
