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.
Actually, a barrel of oil is 42 gallons. When the barrel is processed, you generally get about 19 1/2 gallons of gas, 9 gal. of fuel oil, 4 gal. of jet fuel and 11 gal of other products such as lubricants, grease,kerosene,asphalt and plastics. barrel=42 u.s. gallons of oil =19.5 u.s. gallons of gas Not disputing the answer at all, but if crude is now $135 per barrel, this should make gas nearly $7 per gallon, and this without refining and transport costs!
