Chapter 13.5, Problem 56E

Natural Gas The rate at which natural gas was consumed (in billions of cubic feet per year) by the industrial sector for lease and plant fuel can be approximated by

f ( x ) = 3 x 2 − 14 x + 1131   ( 0 ≤ x ≤ 15 ) ,

where x = 0 corresponds to the start of the year 2000. Find the total consumption (to the nearest billion cubic feet) between the start of 2000 and the start of 2015. (Data from: U.S. Energy Information Administration.)
