Chapter 2.5, Problem 33E

(a)

To determine

A linear function that models the data of U.S. crude oil production, in billions of barrels, with $x$ equal to the number of years past $2010$ and $y$ equal to the number of billions of barrels of crude oil.

(b)

To determine

A quadratic function that models the data of U.S. crude oil production, in billions of barrels, with $x$ equal to the number of years past $2010$ and $y$ equal to the number of billions of barrels of crude oil.

(c)

To determine

To graph: Models obtained in part (a) and (b) and the data on the same axes, with $x$ equal to the number of years past $2010$ and $y$ equal to the number of billions of barrels of crude oil.

(d)

To determine

Whether one model is better visual fit than the other for the given data.
