Chapter 17, Problem 26P

The data below represents the bacterial growth in a liquid culture over a number of days.

Day	0	4	8	12	16	20
Amount $\times {10}^6$	67	84	98	125	149	185

Find a best-fit equation to the data trend. Try several possibilities – linear, parabolic, and exponential. Use the software package of your choice to find the best equation to predict the amount of bacteria after 40 days.
