Finding the Domain Without the Graph. OK, so suppose we don't have the graph of a function to look at like in the last section... Can we still find the domain and range? So, we'll just be doing domains on these -- which is really where the action is anyway. Asking for the domain of a function is the same as asking. What are all the possible x guys.
1 barrel of crude oil = 42 US gallons (159 liters or 35 imperial gallons). It produces from about 35 percent to 42 percent of gasoline or petrol, plus many other products such as kerosene, etc.
A: NOT 33 gallons -- 42 gallons per barrel makes about 19 gallons of gasoline, 9 gallons of fuel oil, 4 gallons of jet fuel, and 11 gallons of other products, including lubricants, kerosene, asphalt, and petrochemical feedstocks to make plastics.t 19.5 gallons of gasoline per barrel, this means that a gallon of gasoline in its crude oil form costs $1.90. Yet, when I pump it into my car, I'm currently paying $1.76 per gallon.
