Chapter 2.2, Problem 72E

E-Filing The table shows the numbers of tax returns (in millions) made through e-file from 2007 through 2014. Let f t represent the number of tax returns made through e-file in the year t .

Chapter 2.2, Problem 72E, E-Filing The table shows the numbers of tax returns (in millions) made through e-file from 2007 , example  1

(a) Find f 2014 f 2007 2014 2007 and interpret the result in the context of the problem.

(b) Make a scatter plot of the data.

(c) Find a linear model for the data algebraically. Let N represent the number of tax returns made through e-file and let t = 7 correspond to 2007.

(d) Use the model found in part (c) to complete the table.

Chapter 2.2, Problem 72E, E-Filing The table shows the numbers of tax returns (in millions) made through e-file from 2007 , example  2

(e) Compare your results from part (d) with the actual data.

(f) Use a graphing utility to find a linear model for the data. Let x = 7 correspond to 2007. How does the model you found in part (c) compare with the model given by the graphing utility?
