(a) Use a graphing utility to plot the data. Let t represent the year, with t = 5 corresponding to 1995.
(b) A model for the data is
5 ≤ 1 ≤ 21
where t = 5 corresponds to 1995. Use the model to estimate the numbers of alternative-fueled
vehicles in 1996, 2006, and 2011. How do your answers compare to the original data?
(c) Use a graphing utility to graph the function with the original data.
