Soit la fonction définie pour tout réel \( \times \) par : \( f(x)=3 x^{3}-x+10 \) Calculer le taux de variation de \( f \) entre -2 et 2 . Entrez votre réponse : Taux de variation =

tvo: Work out Find the quadratic approximation of the function \( \sqrt{1}+x \) at \( \times \) close to 0 ?

\( \int \frac { d x } { x ^ { r } + 4 x + 11 } \)

The area of a rectangular cross-section of a solid is given by the dimensions in terms of a linear function: width = \(x\) and height = \(3 - x\) for \(0 \leq x \leq 3\). Calculate the volume of the solid when these rectangles are stacked from \(x=0\) to \(x=3\).

\( \left. \begin{array} { l } { f ^ { \prime } ( x ) = 4 \sqrt { x ^ { 3 } } + k x ^ { - 2 } } \\ { f ^ { \prime \prime } ( x ) = } \end{array} \right. \)

\( \left. \begin{array} { l } { f ^ { \prime } ( x ) = 4 \sqrt { x ^ { 3 } } + k x ^ { - 2 } } \\ { f ^ { \prime \prime } ( x ) = } \end{array} \right. \)
