Answer
$7.98$ billion pounds of cheese
Work Step by Step
We are given that the function $f(x)=.0007x^{2}+.24x+7.98$ can be used to approximate the total cheese production in the United States from 2000 to 2009, where x is the number of years after 2000 and $y=f(x)$ is pounds of cheese (in billions).
To approximate the number of pounds of cheese produced in the US in 2000, we will use $x=0$.
$f(0)=.0007(0)^{2}+.24(0)+7.98=7.98$ billion pounds of cheese
