Consider the followinggraph of the function f(x) for -0 < x < +0: 1 X 1 L Xx 0 y = f(x) X Xz Key values of x on the graph are labelled x1, x2, x3, x4 and x5. State the values of x at which the following are true: a) f'(x) = 0 b) f'(x) = 0 State the intervals in which both of the following conditions are true: c) f(x)> 0 and f"(x) > 0 d) f'(x) > 0 and F"(x) < 0 e) f'(x) < 0 and f(x) > 0 f) f(x) < 0 and f'(x) < 0 Consider the followinggraph of the function f(x) for -0 < x < +0: 1 X 1 L Xx 0 y = f(x) X Xz Key values of x on the graph are labelled x1, x2, x3, x4 and x5.
