The senior members of the glee club went on 5 field trips during the school year. The number of vans needed to transport the members on each trip is a function of the number of members
who went on each trip. This function consists of only the ordered pairs
(12,1), (28,2), (35,3), (42,3), and (50,4). What is the range for this situation?
A {12, 50)
B {1, 2, 3, 4)
c (12, 28, 35, 42, 50)

D {1, 2, 3, 4, 12, 28, 35, 42, 50}
PLEASE HELP A SIS OUT
