Para encontrar \( f \circ g(x) \), precisamos substituir \( g(x) \) na função \( f(x) \). Primeiro, calculamos \( g(x) \): \[ g(x) = 2x - 3 \] Agora, substituímos \( g(x) \) na função \( f \): \[ f(g(x)) = f(2x - 3) \] Usando a definição de \( f(x) = 3x + 4 \), temos: \[ f(2x - 3) = 3(2x - 3) + 4 \] Vamos simplificar isso: \[ = 6x - 9 + 4 \] \[ = 6x - 5 \] Portanto, o resultado de \( f \circ g(x) \) é: \[ f \circ g(x) = 6x - 5 \]
