Sample Questions A. I notice that f is decreasing at x = -8. State and show the property of your f' graph that corresponds to this fact. B. I notice that you've drawn f above the x - axis between x = -6 and x = 2. Why did you do this? C. Why have you drawn an x - intercept on the graph of f' at x = 10? D. Why is it appropriate for the graph of f to be farther away from the x - axis at x = 6 compared to x = -4? E. If we assume that the graph of f has a horizontal asymptote of y = 2, should the graph of f touch the x - axis as we look farther to the right? Explain your
