$g(9)=28.67$ This tells us that 28.67 percent of college students are taking at least one online course in 2009 (which is x=9 years after 2000).

Work Step by Step

We can find $g(9)$ by plugging $x=9$ into the given equation for $g(x)$. $g(x)=0.07x^{2}+1.9x+5.9$ $g(9)=0.07(9)^{2}+1.9\times9+5.9=0.07\times9\times9+17.1+5.9=5.67+17.1+5.9=28.67$
