The polynomial 0.0011x^3 - 0.07x^2 + 1.7x + 13 models natural gas consumption in trillions of cubic feet, where x equals = 0 corresponds to 1960, x equals = 1 to 1961, and so on.
In which year between 1970 and 1990 was natural gas consumption about 25.7 trillion cubic feet?
OMG I hate this crap. Not really I just hate that it makes me feel like an idiot. Any advice?
Cant I just rewrite it like so?
0.0011x^3 - 0.07x^2 + 1.7x + 13 - 25.7 = Year
