For any item 5 pounds or greater, the following equation gives the price, p(w), of shipping the item between two locations as a function of the item's weight, w, in pounds. Then, the equation is for w>=5 (pounds).

The company does not use the following equation to determine shipping prices for items which are greater than 80 pounds. Then, the equation is used for
w<=80 (pounds)

The domain of p(w) is the values we can give to w, then
Domain of p(w) is 5<=w<=80
Domain of p(w) = [5, 80]

Domain of p(w) = [5, 80]
