Answer

\( f \circ g(x) = 6x - 5 \)

Solution

Para encontrar \( f \circ g(x) \), primero necesitamos entender que esto significa que vamos a evaluar la función \( f \) en la función \( g(x) \). Es decir, vamos a sustituir \( g(x) \) en \( f(x) \). 1. **Identificar las funciones:** - \( f(x) = 3x + 4 \) - \( g(x) = 2x - 3 \) 2. **Sustituir \( g(x) \) en \( f(x) \):** \[ f \circ g(x) = f(g(x)) = f(2x - 3) \] 3. **Sustituir \( 2x - 3 \) en \( f(x) \):** \[ f(2x - 3) = 3(2x - 3) + 4 \] 4. **Realizar la multiplicación y simplificar:** \[ = 6x - 9 + 4 \] \[ = 6x - 5 \] Por lo tanto, la composición de las funciones es: \[ f \circ g(x) = 6x - 5 \]

Para encontrar \( f \circ g(x) \), primero debemos sustituir \( g(x) \) en \( f(x) \). Sabemos que: \[ g(x) = 2x - 3 \] Ahora sustituimos esto en \( f(x) \): \[ f(g(x)) = f(2x - 3) \] Entonces, usando la función \( f(x) = 3x + 4 \), tenemos: \[ f(2x - 3) = 3(2x - 3) + 4 \] Ahora, multiplicamos: \[ = 6x - 9 + 4 \] Simplificamos: \[ = 6x - 5 \] Así que \( f \circ g(x) = 6x - 5 \).
