Answer

Explanation:

Step1: Identificar los valores

Tomamos $x_1 = 1$, $f(x_1)=20$, $x_2 = 5$, $f(x_2)=60$.

Step2: Aplicar la fórmula de tasa de cambio promedio

La fórmula de la tasa de cambio promedio de una función $y = f(x)$ entre $x_1$ y $x_2$ es $\frac{f(x_2)-f(x_1)}{x_2 - x_1}$. Sustituyendo los valores, tenemos $\frac{60 - 20}{5 - 1}$.

Step3: Realizar el cálculo

$\frac{60 - 20}{5 - 1}=\frac{40}{4}=10$.
