\begin{document}

\begin{abstract}
  The point here is to include some programming exercises.
\end{abstract}

\begin{exercise}
Given that $s(k)=-k^2-4 k+2$, evaluate $s(4.5)$. Express your answer in decimal notation.
\begin{solution}
\begin{hint}
$s(4.5)=-(4.5)^2-4 (4.5)+2$.
\end{hint}
\begin{hint}
$s(4.5)=-36.25$.
\end{hint}
The value of the function $s(k)=-k^2-4 k+2$, evaluated at $k=4.5$, is \answer{-36.25}.
\end{solution}

Here is some text after the first problem.
\end{exercise}

\begin{exercise}
Write a function $f$ so that $f(2) = 4$.

\begin{solution}
\begin{python}
def f(x):
  # this is where you should include your code
  return x

def validator():
  return (f(2) == 4)
\end{python}
\end{solution}

So you did it.  Great!
\end{exercise}
