The total projected worldwide digital music revenues, R, in millions of dollars, for the
years 2005 through 2010 can be represented by the function
R(x) = 1.70.7x^2+ 1373x + 1080
where x is the number of year after 2005.
(a) Find R(0)and R(5) and explain what each value represents.
(b) Find r = R(x – 5)
(c) Find r(5) and explain what this value represents.
(d) In the model r, what does x represent?
(e) Would there be an advantage in using the model r when estimating the projected
revenues for a given year instead of the model R?
