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.
1 barrel = 42gal, and 128oz in 1 gal, so 128 x 21 = 2688oz in a half barrel. ----Oops... that's a oil barrel... # UK beer barrel: 36 UK gallons (163.7 litres). # US beer barrel: 31Â½ U.S. gallons (117.3 litres), the result of tax law definitions.
