Ruby is having a Hot Dog party. She has 15 hot dogs but needs to purchase more hot dogs. She can
purchase up to 8 boxes of hot dogs. Each box contains 32 hot dogs. Ruby cannot purchase partial
boxes. The function that models the number of hot
dogs Ruby has is f(b) = 32b + 15, where b is the number of hot dogs purchased.
What is the practical domain and range of the function ?
