= A(2) Two niche social networking companies, one for financial advisors and one for accountants, generate revenue from rich media advertisements. The function F(x) 3x2 + 11 models the revenue (in millions of dollars) for the financial advisors network for the years 2007 to 2012. The function A(z) x2 + 5 models the F(x) revenue (in millions of dollars) for the accountants network for the years 2007 to 2012. The ratio R(x) F(x) is a measure of the size of F(x) relative to A(x). For example, if R(x) 3, then F(x) = 3 A(2) A(2) and you can see that F(x) is three times the size of A(x). That is, the revenue realized by the financial advisors network is three times the revenue realized by the accountants network. (Assume x is the number of years from January 1, 2007.) - a. How does the revenue of the financial advisors network compare to that of the accountants niche in 2009? Round to 2 decimal places. F(x) A(2) b. Write an expression for the rate at which the ratio of revenues changes as the number of years from 2007 changes. R'(x)= Preview c. At what rate is the ratio changing in the year 2009? Round to 2 decimal places
