So in this problem, we are given the polynomial negative 1 ,264 x squared plus 5 ,056x plus 18 ,960, get that comma out, describes the cotton harvest on the years from 2003 to 2007.
00:24
So the first question asked to find the cotton harvest in 2013.
00:32
In 2004.
00:35
And for that, it says let x equal 1.
00:38
Because x equals 0, it's correspond to that first year of 2003 to 2007.
00:47
So all you would have to do is go into that equation and substitute 1 for x.
00:56
And putting that into your calculator, you should get 22.
01:02
Thousand seven hundred and fifty two.
01:06
B part says find the approximate amount in 2007 so if you think about that if 2003 or 2004 is one and the 2005 would be two, 2006 would be three and 2007 would be four so you would want to let equals 4 in your equation.
01:38
So that would be negative 1 ,264 times 4 squared plus 5 ,056 times 4 plus 18 ,960, which would be 18960.
01:59
And then finally it says to factor the polynomial...
