Rocky has 7 bottles of water. He will buy more bottles of water from the store. The store has 8 cases in stock and each case contains 24 bottles of water. The store will not sell partial cases. The function that models the number of bottles of water Rocky will have after his purchase is  f(c)=24c+7, where c is the number of cases of water he buys.

What is the practical domain of the function?

What is the practical range of the function?

A caterer has 5 rolls. He is ordering more rolls. He can order up to 9 packages of rolls and each package contains 12 rolls. The caterer cannot order partial packages. The function that models the number of rolls the caterer has is  f(p)=12p+5, where p is the number of packages he orders.

Domain  = number of possible cases he could buy  =  0  to 8

Range. =   nubmer of possible bottles of water he could have  =

7   to   [ 24(8)  + 7 ]  =     7 to  199

Domain  = number of possible packages he could buy =  0 to 9

Range  =  number of possible rolls  =

5  to  [ 12(9) + 5 ]   =     5 to  113
