A textbook company will ship a box of textbooks to college students. The weight of the box in pounds can be determined by the function w(x) = 7.5x + 2, where x is the number of textbooks in the box. The company requires a student to order at least 2 books but not more than 6 books. What is the range of the function for this situation? *

A. 2 ≤ x ≤ 6

B. 17 ≤ y ≤ 47

C. {17, 24.5, 32, 39.5, 47}

D. {2, 3, 4, 5, 6}
