3. Determina el recorrido de cada función. Justifica en cada caso. a. Sea la función \( f(x)=x+8 \), y su dominio los números pares mayores que 5 y menores que 15 . b. Sea la función \( f(x)=\frac{x+6}{3} \), y su dominio esté formado por los múltiplos de 3 menores que 30 y mayores o iguales que 15 .

Answer

- **Recorrido de \( f(x) = x + 8 \):** \( \{14, 16, 18, 20, 22\} \) - **Recorrido de \( f(x) = \frac{x + 6}{3} \):** \( \{7, 8, 9, 10, 11\} \)

Beyond the Answer

Para la función \( f(x)=x+8 \) con dominio de números pares mayores que 5 y menores que 15 (6, 8, 10, 12, 14), el recorrido se determina al evaluar estos valores: - \( f(6) = 14 \) - \( f(8) = 16 \) - \( f(10) = 18 \) - \( f(12) = 20 \) - \( f(14) = 22 \) Por lo tanto, el recorrido es \( \{14, 16, 18, 20, 22\} \). Para la función \( f(x)=\frac{x+6}{3} \) y un dominio de múltiplos de 3 en el rango de 15 a 30 (15, 18, 21, 24, 27), calculamos: - \( f(15) = 7 \) - \( f(18) = 8 \) - \( f(21) = 9 \) - \( f(24) = 10 \) - \( f(27) = 11 \) El recorrido de esta función es \( \{7, 8, 9, 10, 11\} \).
