Chapter 1.2, Problem 8E

Gross Domestic Product The following table shows the U.S gross domestic product (GDP) $G$, in trillions of dollars, as a function of the year $t$.

$t=\text{Year}$	$2004$	$2010$	$2014$
$\begin{array}{l}G=GDP\\ \text{(trillion}\text{of}\text{dollars)}\end{array}$	$11.87$	$14.66$	$17.42$

a. Explain in practical terms what $G\left(2004\right)$ means, and find its value.

b. Use functional notation to express the gross domestic product in $2007$, and estimate that value.

c. What is the average yearly rate of change in $G$ from $2010$ to $2014$?

d. Use your answer to part c to predict the gross domestic product in the year $2022$.
