the function $y = f(x)$ is graphed below. what is the average rate of change of the function $f(x)$ on the interval $4leq xleq6$?

the function $y = f(x)$ is graphed below. what is the average rate of change of the function $f(x)$ on the interval $4leq xleq6$?

Answer

Explanation:

Step1: Identificar la fórmula

La tasa media de cambio de una función $y = f(x)$ en el intervalo $[a,b]$ está dada por $\frac{f(b)-f(a)}{b - a}$. Aquí, $a = 4$ y $b=6$.

Step2: Leer valores del gráfico

Observando el gráfico, $f(4)=8$ y $f(6)= - 4$.

Step3: Calcular la tasa media de cambio

Sustituimos en la fórmula: $\frac{f(6)-f(4)}{6 - 4}=\frac{-4 - 8}{2}=\frac{-12}{2}=-6$.

Answer:

$-6$
