Worldwide oil production. One model of worldwide oil production is P ( t ) = 2.69 t 4 − 63.941 t 3 + 459.895 t 2 − 688.692 t + 24 , 150.217 , where P ( t ) is the number of barrels, in thousands, produced t years after 2000. ( Source : Based on data from the U.S. Energy Information Administration.) According to this model, in what year did worldwide oil production achieve an absolute minimum? What was that minimum?
