n admet que la concentration, exprimée en \( m g . L^{-1} \), du produit a ans le sang du malade est donnée en fonction du temps \( t \), exprime \[ f(t)=t^{3}-12 t^{2}+36 t \] Calculer par la fonction \( f(2) \) définie sur l'intervalle \( [0 ; 6] \) par : a. On note \( f^{\prime} \) la fonction dérivée de la fonction \( f \) sur l'inter ; 6]. Calculer \( f^{\prime}(t) \)

Calculate the area under the curve defined by the function \( f(x) = x^3 + 2x - 1 \) from \( x = 1 \) to \( x = 3 \).

Find Relative Extreme values of \( F(x)=2 x^{3}-9 x^{2}-24 \)

Dada la funcion implicita: \( \frac{1}{x}=\frac{4^{x}}{8^{y}} \)

Solve the following exponential equation. Express the solution set in terms of natural logarithms or common logarithms. Then, use a calculator to obtain a decimal approximation for the solution. \( e^{1-5 x}=851 \) The solution set expressed in terms of logarithms is (Use a comma to separate answers as needed. Simplify your answer. Use integers or fractions for any numbers in the expression. Use In for natural logarithm and log for common logarithm.) Now use a calculator to obtain a decimal approximation for the solution. The solution set is \{ (Use a comma to separate answers as needed. Round to two decimal places as needed.)

3. If \( F(x)=x^{3}+a x+b \) has relative miclimum value of - 6 at \( x=\partial \) firld the value af " \( a \) " and " \( b \) "
