Question 1046862: I'm having quite a bit of trouble understanding this question on my homework. Can someone help me out?
The graph shows the sales (in millions of dollars) of Peet's Coffee & Tea from 2000 through 2008. Let f(x) represent the sales in year x.
a) Find (f(2008) - f(2000) )/ (2008 - 2000) and interpret the results in the context of the problem.
b) An approximate model for the function is S(t) = 2.48t2 + 5.71t + 84.0 where 0 ≤t ≤8
where S is the sales (in millions of dollars) and t = 0 represents 2000. Complete the table and compare the results with the data in the graph.

The graph shows the sales (in millions of dollars) of Peet's Coffee & Tea from 2000 through 2008. Let f(x) represent the sales in year x.
a) Find (f(2008) - f(2000) )/ (2008 - 2000) and interpret the results in the context of the problem.
I used the equation (below) and found f(2008) = 10 million; f(2000) = 9.93 mill.
Ans: 0.07/8 = $0.00875 million = $8750

b) An approximate model for the function is S(t) = 2.48t^2 + 5.71t + 84.0 where
0 ≤ t ≤8 where S is the sales (in millions of dollars) and t = 0 represents 2000. Complete the table and compare the results with the data in the graph.
