Applied question - Quadratic model of Concentration of Atmospheric $CO_2$

SOLUTION ====================

This question was probably confusing because of the language. 
It was simply a matter of substituting the value $x=2010$ into the equation 
so, $f(2010) = 0.0167*2010^2-65.37x+64440$
$=  515.97 ~ 516$ ppm
