\begin{questions}

\item\PTs{6} If $\lim_{x\to a} f(x) = f(a)$, then we say that $f$
is\dots

    \Ans0 differentiable\eAns
    \Ans1 continuous\eAns
    \Ans0 integrable\eAns
\eChoices
%\Ans0 differentiable &\Ans1 continuous &\Ans0 integrable
\end{answers}
\begin{solution}
A function $f$ is said to be continuous at $x=a$ if $x\in\operatorname{Dom}(f)$,
$\lim_{x\to a} f(x) $ exists and $\lim_{x\to a} f(x) = f(a)$.
\end{solution}


\item\PTs{6} Name \emph{one} of the two people recognized as a founder of
Calculus.
\RespBoxTxt{0}{0}[calc]{4}{Isaac Newton}{Newton}{Gottfried Leibniz}{Leibniz}%
\CorrAnsButton{Isaac Newton or Gottfried Leibniz}
\begin{solution}
Isaac Newton and Gottfried Leibniz are the co-creators of Calculus.
\end{solution}


\item\PTs{8} $\dfrac{\text{d}}{\text{d}x} e^{x^2} = $\ \RespBoxMath{2*x*e^(x^2)}[diffexp]{4}{.0001}01
\CorrAnsButton{2*x*e^(x^2)}
\begin{solution}
First apply the rule for differentiating an the natural exponential, then apply
the power rule:
\begin{align*}
        \dfrac d{dx}\,e^{x^2} &
           = e^{x^2}\,\dfrac d{dx}\,x^2 \\&
           = e^{x^2}\,(2x) \\&
           = 2x e^{x^2}
\end{align*}
In the syntax of this document, \js{2*x*e^(x^2)}.
\end{solution}
