\item The figure below shows the graph of a function~$f'$ to scale. In
  the grid provided, carefully sketch the graph of~$f$, assuming that
  $f(0)=0$. Plot any critical points first; then fill in the rest of
  the graph, paying attention to signed area and the vertical scale.

\item Repeat the previous question, using the grid to estimate signed
  areas as well as you can. Note: Each grid square is
  $\frac{1}{4}\times\frac{1}{4}$. How many squares give a rise/drop of
  one grid line?
