\begin{exercice} \label{1SF4_E_asso}
On donne ci-dessous les courbes $\mathcal{C}_1$, $\mathcal{C}_2$ et $\mathcal{C}_3$ représentant trois fonctions définies et dérivables sur $\mathbb{R}$, ainsi que $\Gamma_1$, $\Gamma_2$ et $\Gamma_3$ représentant leur dérivée.

  \begin{tikzpicture}[general, scale=0.8]
   \draw [quadrillage] (-2,-4)grid (3,2);
   \axeX{-2}{3}{1}
   \axeY{-4}{2}{1}
   \origine
   \draw [domain=-2:0.91, color=B1, smooth] plot(\x,{((\x)^3+3*(\x)^2+3*\x)/3});
   \draw (1.5,1.5) [color=B1] node{{\boldmath $\mathcal{C}_3$}};
   \draw [domain=-2:3, color=D1, smooth] plot(\x,{(2*(\x)^3-3*(\x)^2-12*\x)/6});
   \draw (1.5,-3.5) [color=D1] node{{\boldmath $\mathcal{C}_2$}};
   \draw [domain=-0.64:3, color=G1, smooth] plot(\x,{-(2*(\x)^3-9*(\x)^2+12*\x)/6});
   \draw (1.5,-1.5) [color=G1] node{{\boldmath $\mathcal{C}_1$}};
  \end{tikzpicture}
  \begin{tikzpicture}[general, scale=0.8]
   \draw [quadrillage] (-2,-3)grid (3,3);
   \axeX{-2}{3}{1}
   \axeY{-3}{3}{1}
   \origine
   \draw [domain=-2:0.74, color=J1, smooth] plot(\x,{(\x+1)*(\x+1)});
   \draw (1.5,2.5) [color=J1] node{{\boldmath $\Gamma_2$}};
   \draw [domain=-1.79:2.79, color=H1, smooth] plot(\x,{(\x+1)*(\x-2)});
   \draw (1.5,-2.5) [color=H1] node{{\boldmath $\Gamma_3$}};
   \draw [domain=-0.3:3, color=F1, smooth] plot(\x,{-(\x-1)*(\x-2)});
   \draw (1.5,0.5) [color=F1] node{{\boldmath $\Gamma_1$}};
  \end{tikzpicture}
 
Associer, en justifiant, les courbes par binôme.
