The total projected worldwide digital music revenues R, in millions of dollars, for the years 2005 through 2010 can be estimated by the function
R(x) = 170.7x^2 + 1373x + 1080 where x is the number of years after 2005.
(a) Find R(0), R(3) and R(5),represents. Explain what each value represents.
(b) Find r = R(x- 5).
(c) Find r(5), r(8), and r(10), and explain what each value represents.
(d) In the model r, what does x represent?
Let me see.
Part A
I simply replace x with 0, 3, and 5 but I have no idea what each value represents.
Part B
Can you set it up for me?
Part C
I think r(5) represent the year 2005, r(8) represents the year 2008 and r(10) represents the year 2010.
You say?
Part D
I need the model r to guess what x represents.
