\noindent 
When using \LaTeX\ , you can drop a tex file into a problem by invoking the pictex package. The code in the preamble is:


\bigskip


\hspace*{.5in}$\backslash$usepackage\{pictex\}

\prob{Consider the graph of $y = f'(x)$

\centerline{ \input testpict1.tex }

\bigskip

State all the intervals where $f(x)$, the original function, is increasing.

\vspace{.5in}


State all the intervals where $f(x)$ is decreasing.


\vspace{.5in}

Draw an approximate graph of $y = f''(x)$.  Indicate your scales.

\vspace{2in}



State all the intervals where $f(x)$ is concave up.

The above graph was included in the file with the following code:
