a) To find an exponential function, base e, that fits the data, find k using the points
Chapter 3, Problem 26(choose chapter or problem)
a) To find an exponential function, base e, that fits the data, find k using the points (10, 280) and (15, 406). Then write the function. (Assume that x is the number of years after 1990.) b) Estimate the total sales of paper shredders in 2007 and in 2012. c) After what amount of time will total sales be $500 million? d) What is the doubling time for sales of shredders? e) Compare your answers to parts (a)(d) with those from Exercise 25. Decide which exponential function seems better to you, and explain why.
