Assignment:
Two models, R1 and R2, are given for the revenue (in billions of dollars per year) for a large corporation.
Both models are estimates of revenues for 2004-2008, with t = 4 corresponding to the year 2004.
Which model is projecting the greatest revenue?
How much more revenue does that model project for the four year period?
R1(x) = 7.21 + 0.26t + 0.02t2, R2(x) = 7.21 + 0.1t + 0.01t2
Provide complete and step by step solution for the question and show calculations and use formulas.
