The following table shows fuel consumption in billions of gallons of all vehicles in the U.S. for years since 1990.

Year Fuel Use
0 130.8
3 137.3
6 147.4
9 161.4
12 168.7
15 174.8
18 170.8


Let F(t) be the fuel consumption in billions of gallons in t years since 1990. A quadratic model for the data is F(t)=−0.114t2+4.62t+127.598.

Use the above scatter plot to decide whether the quadratic model fits the data well.

The function is a good model for the data.
The function is not a good model for the data

Correct
Estimate the fuel consumption in the U. S. in 2009. Correct billions of gallons.
Use the model to predict the (whole) year in which U.S. fuel consumption will peak. Do not write decimals.
