Modelling Exponential Data



We will work through the following example together in class:

I have invested $1,000,000 dollars for 90 years as shown in the data below. You will analyze the data in three different manners.



year 0 10 20 30 40 50 60 70 80 90
amount (in millions $) 1.000 2.16 4.66 10.06 21.73 46.902 101.53 218.61 471.96 1018.92




Analysis #1

(a) Create a hand drawn scatter plot of the financial data.

(b) Algebraically, determine an equation for the "curve of best fit" (HINT: ratios)





Analysis #2

(c) Graph the data using technology (WINSTAT or GC) and determine the regression equation of best fit. Determine the coefficient of determination/correlation. Print the graph





Analysis #3

(d) Graph the data on semi-log paper. Determine the equation of the line of best fit. Rearrange this equation to an exponential equation. Show work. You can get more semi-log paper by following this link





(e) What is the annual rate of growth of this investment?
