Answer

Explanation:

Step1: Definir tasa de cambio promedio

La tasa de cambio promedio de una función $y = f(x)$ en el intervalo $[a,b]$ está dada por $\frac{f(b)-f(a)}{b - a}$. Si $\frac{f(b)-f(a)}{b - a}<0$, la tasa de cambio promedio es negativa.

Step2: Analizar intervalo [1,3]

Supongamos que para $x = 1$ y $x = 3$, si $f(3)<f(1)$ (lo que significa que la función está decreciendo en el intervalo), entonces $\frac{f(3)-f(1)}{3 - 1}<0$.

Step3: Analizar intervalo [6,7]

Si $f(7)<f(6)$ en el intervalo $[6,7]$, entonces $\frac{f(7)-f(6)}{7 - 6}<0$.

Step4: Analizar otros intervalos

Para el intervalo $[0,1]$, si $f(1)>f(0)$ la tasa de cambio promedio es positiva. Para el intervalo $[3,4]$, si $f(4)>f(3)$ la tasa de cambio promedio es positiva.

Answer:

The average rate of change is negative on the interval $[1,3]$ and also on the interval $[6,7]$.
