Solution 9 du défi 11 \( \begin{array}{l}\text { 1. } x<2 \Longrightarrow f(x)<f(2) \Longrightarrow f(x)<7 \\ \text { 2. } x<6 \Longrightarrow f(x)>f(6) \Longrightarrow f(x)>8 \\ \text { 3. }-3<x<9 \Longrightarrow f(-3) \leq f(x) \leq f(9) \Longrightarrow-5 \leq f(x) \leq 9 \\ \text { 4. }-6<x<2 \Longrightarrow f(-6) \geq f(x) \geq f(2) \Longrightarrow 5 \geq f(x) \geq 3\end{array} \)
