\begin{exercice}
 Même consigne qu'à l'exercice \RefExercice{1SF4_E_var_fct_courbe}.
 \begin{center}
  \begin{tikzpicture}[general, scale=1]
   \draw [quadrillage55, line width = 0.1mm] (-2,-2) grid (3,2);
   \draw [quadrillage] (-2,-2) grid (3,2);
   \axeX{-2}{3}{1}
   \axeY{-2}{2}{1}
   \origine
   \draw [domain=-1.5:2.24, color=J1, smooth] plot(\x,{((\x)^2*(\x+1)*(\x-2)/2});
   \draw (1.5,0.5) [color=J1] node{{\boldmath $\mathcal{C}_{f'}$}};
   \end{tikzpicture}
 \end{center}
