1. A set of weights includes a 5 lb barbell and 5 pairs of weight plates. Each pair of plates weight 30 lb. If x pairs of plates are added to the barbell,
the total weight of the barbell and plates in pounds can be represented by
f(x) = 30x + 5.
What is the range of the function for this situation?
A {0,1,2,3,4,5,}
B {5, 35, 65,95, 125, 155)
C {0,1,3,5)
D (5,65, 125, 155)
Please help!!!
