The employment rate in a city has been documented at two year intervals. The table shows the number of employed citizens, in millions, tor several years, with 2000 represented by year 0,2002 by year 2 , and so on. Use the data points $(0,2.9),(4,2.3)$, and $(8,3.0)$ to find a quadratic function defined by $f(x)=a x^{2}+b x+c$ that models the data. Graph $f$ together with the data.
