Answer

Explanation:

Step1: Definir la fórmula

La tasa promedio de cambio de una función $y = f(x)$ en el intervalo $[a,b]$ está dada por $\frac{f(b)-f(a)}{b - a}$. Aquí, $a = 4$, $b=11$ y $f(x)=\frac{60}{2x - 2}$.

Step2: Calcular $f(4)$

Sustituir $x = 4$ en $f(x)$: $f(4)=\frac{60}{2\times4 - 2}=\frac{60}{8 - 2}=\frac{60}{6}=10$.

Step3: Calcular $f(11)$

Sustituir $x = 11$ en $f(x)$: $f(11)=\frac{60}{2\times11 - 2}=\frac{60}{22 - 2}=\frac{60}{20}=3$.

Step4: Calcular la tasa promedio de cambio

Aplicar la fórmula $\frac{f(b)-f(a)}{b - a}$: $\frac{f(11)-f(4)}{11 - 4}=\frac{3 - 10}{7}=\frac{-7}{7}=- 1$.

Answer:

$-1$
