Question 460032: Hello. Referred to me by Minka.
The polynomial 0.0013x^3 - 0.075x^2 + 1.5x + 11 models natural gas consumption in trillions of cubic feet, where x=0 corresponds to 1960, x=1 to 1961, and so on.
In which year between 1970 and 1990 was natural gas consumption about 23.1 trillion cubic feet?
Truly greatful to whom replies.
