Fitting Exponential Models to Data · Exercise 4

Fit a regression equation to a set of data and use the linear (or exponential) model to make predictions.

Gasoline consumption in the United States has been steadily increasing from 1994 to 2004.

$$\begin{array}{cccccccccccc}\text{Year}& \text{94}& \text{95}& \text{96}& \text{97}& \text{98}& \text{99}& \text{00}& \text{01}& \text{02}& \text{03}& \text{04}\\ \text{Consumption (billions of gallons)}& \text{113}& \text{116}& \text{118}& \text{119}& \text{123}& \text{125}& \text{126}& \text{128}& \text{131}& \text{133}& \text{136}\end{array}$$

ⓐ Determine whether the trend is linear, and if so, use your graphing utility to find a model for the data.
ⓑ Use the model to predict the consumption in 2008.

Its source prints no answer for this problem, so there's nothing to check against.
