The function f gives the number of copies a book has sold w weeks after it was published. The equation f(w) = 500 * 2^w defines this function. Select all domains for which the average rate of change could be a good measure for the number of books sold.

A. 0 ≤ w ≤ 2
B. 0 ≤ w ≤ 7
C. 5 ≤ w ≤ 7
D. 5 ≤ w ≤ 10
E. 0 ≤ w ≤ 10

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
