    We consider the function $f(x)$ with  
    \begin{talign}
      f(x) = \frac{1-x^3}{1+x^3}
      &&
      f'(x) = \frac{6x^2}{(1+x^3)^2}
      &&
      f''(x) = \frac{12x(2x^3-1)}{(1+x^3)^3}
    \end{talign}
    \only<-1>{
    Find all
    \begin{itemize}
      \item horizontal, vertical asymptotes,
      \item the left and right limits at vertical asymptotes,
      \item points with horizontal tangents and local extrema
      \item on which intervals is $f$ increasing/decreasing?
      \item on which intervals is $f$ concave up/down?
      \item inflection points
    \end{itemize}
    Then sketch the graph of $f(x)$.
