Figure 8 shows the estimated number N of Internet users in Chile, based on data from the United Nations Statistics Division.
(a) Estimate the rate of change of N at t = 2003.5.
(b) Does the rate of change increase or decrease as t increases? Explain graphically.
(c) Let R be the average rate of change over [2001, 2005]. Compute R.
(d) Is the rate of change at t = 2002 greater than or less than the average rate R? Explain graphically.
