Pour trouver \( f \circ g(x) \), nous devons d'abord évaluer \( g(x) \) puis substituer ce résultat dans \( f(x) \). 1. Calculez \( g(x) \): \[ g(x) = 2x - 3 \] 2. Substituez \( g(x) \) dans \( f(x) \): \[ f \circ g(x) = f(g(x)) = f(2x - 3) \] 3. Maintenant, remplacez \( x \) dans \( f(x) = 3x + 4 \) par \( 2x - 3 \): \[ f(2x - 3) = 3(2x - 3) + 4 \] 4. Simplifiez: \[ = 6x - 9 + 4 \] \[ = 6x - 5 \] Donc, \( f \circ g(x) = 6x - 5 \).
