A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs 20 lbs. 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) = 20x + 4.

What is the range of the function for this situation?

• {0, 1, 2, 3, 4, 5, 6}

• {4, 24, 44, 64, 104, 124}

• {0, 2, 4, 6}

• {4, 44, 84, 124}
