Chapter 4.5, Problem 68E
In Example 1 on page 520, we used two data points and an exponential function to model the population of the United States from 1970 through 2010. The data are shown again in the table. Use all five data points to solve Exercises 66–70.
68. Use your graphing utility’s linear regression option to obtain a model of the form y = ax + b that fits the data. How well does the

The equation ŷ = 12(0.81)x is a model that fits the data. Which of the following uses the model correctly and is an example of extrapolation?
A patron who has been using the library for 2 years is predicted to have between 7 and 8 overdue books.
A patron who has been using the library for 13 years is predicted to have between 6 and 7 overdue books.
A patron who has been using the library for 2 years is predicted to have more than 94 overdue books.
A patron who has been using the library for 13 years is predicted to have less than 1 overdue book.
