In 1956, M. King Hubbert proposed a model to analyze crude oil production. His model, with updated data, gives world crude oil production as -0.042r 254.43e (1+2.12e-0.0422 Here P is measured in billions of barrels per year, and this time, in years, since 2000. (a) Make a graph of world crude oil production for 2000 through 2040. P P 35 30 25 20 19 15 10 St P 35 0 25 20 35 30 25 19 10 P=.

(Round your answer to the nearest whole number.) 19 (c) What is the maximum crude oil production predicted by this model?
