Joe has 20 hot dogs. he is purchasing more hot dogs. he can purchase up to 8 boxes of hot dogs. each box contains 48 hot dogs. joe cannot purchase partial boxes. the function that models the number of hot dogs joe has is f(b)=48b+20f(b)=48b+20 , where b is the number of boxes of hot dogs he purchases. what is the practical domain of the function? all real numbers from 1 to 8 inclusive {68,116,164,212,260,308,356,404}{68 ,116,164,212,260,308,356,404} all integers from 1 to 8 inclusive all real numbers

Step-by-step explanation:

We know that:

We can observe that the domain of the given function is all values for , and its range is represented by all the values of .

So, all practical values that should belong to the domain set is from 1 to 8, only integers numbers, because the problem says that Jose cannot buy incomplete boxes. Therefore, the answer is "all integers from 1 to 8".

It's important to notice that the domain represent the amount of boxes, and the range represent the total number of hot dogs, that's why the domain should be restricted only from 1 to 8, because he can by minimum one box, and maximum 8 boxes.
