Voici un programme de calculs. \begin{tabular}{l|l} On note \( f \) la fonction qui au nombre \( x \) choisi au départ associe le résultat & - Choisir un nombre \\ obtenu par le programme de calcul. & - Calculer son carré \\ Ecrire, en fonction de \( x \), l'expression algébrique \( f(x) \) de la fonction \( f \) & - Multiplier par 5 \\ (se lit " \( f \) de \( x^{\text {"}} \) ) & - Ajouter 10\end{tabular}

3. \( 3 x(4 x-5) \)

-11) \( \frac{22^{4} \cdot 8^{4}}{121^{4} \cdot 4^{6}}= \)

\( 19 j-86 \geq 5 \) or \( 27 j-82 \leq 18 \)

QUESTION 3 3.1 Given the number pattern \( 2 ; y ; 8 ; \ldots \) Determine the value of \( y \) if: 3.1.1 The number pattern is linear. 3.1.2 The number pattern is quadratic and \( T_{4}=2+5 y \). 3.2 In a linear number pattern, the \( 19^{\text {th }} \) term is 40 and the \( 7^{\text {th }} \) term is 16 . Thus, determine the first two terms. 3.3 The general term of a quadratic number pattern is \( T_{n}=n^{2}+2 n-15 \). Determine which term has a value of 20 .
