  For local minima and maxima:
  \begin{itemize}
  \pause
    \item find critical numbers $c$
  \pause
    \item then the first First Derivative Test:
          \begin{itemize}
            \item $f'$ changes from $+$ to $-$ at $c$ $\;\implies\;$ maximum
            \item $f'$ changes from $-$ to $+$ at $c$ $\;\implies\;$ minimum
          \end{itemize} 
  \pause
    \item Second Derivative Test:
          \begin{itemize}
            \item $f''(c) < 0$ $\;\implies\;$ maximum
            \item $f''(c) > 0$ $\;\implies\;$ minimum
            \item $f''(c) = 0$ $\;\implies\;$ use First Derivative Test
          \end{itemize} 
  \end{itemize}

  Then sketch the curve:
  \begin{itemize}
  \pause
    \item draw asymptotes as thin dashed lines 
  \pause
    \item mark intercepts, local extrema and inflection points
  \pause
    \item draw the curve taking into account:
      \begin{itemize}
        \item increase / decrease, concavity and asymptotes
      \end{itemize}
  \end{itemize}
