(2+4+4+4) The growth of a sunflower during the first hundred days after sprouting is plotted below in Figure 2. (a) Plot the point of inflection in Figure 2 below and draw the tangent line to the curve at that point. (b) Estimate the growth rate at the point of inflection. (c) In the space below draw a graph of the derivative of the growth curve. (d) In the space below draw a graph of the second derivative of the growth curve.
