Multiple Choice

Solve the problem
- $$\begin{array} { c | c } & \text { Population } \\\text { Year } & \text { (in millions of people) } \\\hline 0 & 65 \\1 & 65.5 \\2 & 67 \\3 & 69 \\4 & 71.5\end{array}$$ We used this data to develop the quadratic function $$f ( x ) = 0.373 x ^ { 2 } + 0.165 x + 65$$ , which models the population of the city y in millions in the year x. Use the model to find the estimated population in
Year 9.
