You can put this solution on YOUR website!
It is C.
\n" ); document.write( "A and B are both linear models, so they can be excluded. Quadratic models are of the form y=ax^2+bx+c
\n" ); document.write( "This can be entered on a calculator with a quadratic model showing a very high R^2 of 0.98 with those coefficients.
