A set of weights includes a`20`lb barbell and`6`pairs of weight plates. Each pair of plates weighs `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

Question

Does this graph represent a discrete or continuous situati
