The graphs of two functions y = f(x) are shown in Figure 1 below. For each of them, sketch a qualitatively accurate graphs of the first derivative f′(x) and the second derivative f′′(x) from the graphs of f(x).

Question 1 [20 marks] The graphs of two functions y = f(x) are shown in Figure 1 below. For each of them, sketch a qualitatively accurate graphs of the first derivative f'(x) and the second derivative f"(x) from the graphs of f(x). (a) (b) Figure 1: The graph of y = f(r).
