Chapter 3.4, Problem 61E

Software Publishing The table shows the estimate revenues (in billions of dollars) of software publishers in the United States from 2011 through 2013.(Source: U.S. Census Bureau)

Year Revenues, y
2011 156.8
2012 161.7
2013 177.2

(a) Create a system of linear equations for the data to fit the curve

y = a t 2 + b t + c

Where t = 1 corresponds to 2011, and y is the revenue.

(b) Use Cramer’s Rule to solve the system.

(c) Use a graphing utility to plot the data and graph the polynomial function in the same viewing window.

(d) Briefly describe how well the polynomial function fits the data.
