A set of weights includes a 20lb barbell and 6 pairs of weight plates. Each pair of plates weighs 30 lb. If this situation? xpairs of plates are added to the barbell, the total weight of the barbell and plates in pounds can be represented by f(x) = 30x+20.

Q Search
The domain for the function f(x) = 30x + 20 in this situation would be the number of pairs of plates, which is represented by x. Since x can be any non-negative integer, the domain would be {0, 1, 2, 3, 4, 5, 6}.
The range for this function would be the total weight of the barbell and plates, which is represented by f(x). Since the total weight starts at 20 lbs and increases by 30 lbs for each additional pair of plates, the range would be {20, 50, 80, 110, 140, 170, 200}.
