Bus Econ 2.4.101-GC One model of worldwide oil production is the function given by the following formula, where P(t) is the number of barrels, in billions, produced in a year, t years after 1926. According to this model, in what year did worldwide oil production achieve an absolute maximum? What was that maximum? P(t) = -0.000000216t^4 - 0.0000167t^3 + 0.00155t^2 + 0.002t + 0.24, 0 <= t <= 90 According to this model, the absolute maximum amount of oil produced worldwide was billion barrels in the year.
