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.
With 42 gallons in each barrel of oil, a $1 change in the price of a barrel of oil roughly translates to a 2.4-cent change per gallon at the pump. U.S. retail (regular) gasoline prices averaged a record $3.63 in 2012, and are expected to average $3.44 per gallon in 2013.On-road diesel fuel averaged a record $3.97 per gallon in 2012, and is expected to decrease to $3.87 per gallon in 2013.il. Oil demand in 2012 was 89.17 million barrels per day worldwide, an increase of 1.07 million barrels per day over 2011. Demand is projected to increase to 90.11 million barrels per day in 2013 and 91.46 million barrels per day in 2014.
