A shipping company uses the weight of packages to determine shipping prices. 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. The company does not use the following equation to determine shipping prices for items which are greater than 80 pounds.

p (w) = $3.50w+$5.50

determine the domain of p (w).

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]

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