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...
*5. A function f defined on an interval I = {x: a <x<b> is called increasing f(x) > f(x2) whenever xi > X2 where x1, x2 €1. Suppose that has the inter- mediate-value property: that is, for each number c between f(a) and f(b) there is an x, el such that f(x) = c. Show that a functionſ which is increasing and has the intermediate-value property must be continuous. This is from my real analysis textbook, We are establishing the...

At least one of the answers above is NOT correct. (1 point) Suppose /(x) = x + 3x + 1. In this problem, we will show that has exactly one root (or zero) in the interval (-3,-1). (a) First, we show that f has a root in the interval (-3,-1). Since is a continuous function on the interval (-3, -1) and f(-3) = and f(-1) = -1 the graph of y = f(x) must cross the X-axis at some point...
