\begin{enumerate}
\item
  \nbPointsEnumi{2}Give the \(x\)-coordinates of the two turning points.
\item
  \nbPointsEnumi{2}For which values of \(x\) is the graph of \(f(x)\) increasing?
\item
  \nbPointsEnumi{2}For which value of \(x\) does \(f(x)\) reach a minimum?
\item
  \nbPointsEnumi{3}Sketch a possible graph of \(f(x)\), given that the point \((8,0)\)
  lies on the graph of \(f(x)\).
