Question
the function f is defined as follows.
$f(x)=\sqrt3{x - 8}$
find $f(8)$ and $f(-117)$.
$f(8)=\square$
$f(-117)=\square$
Step1: Calcular \( f(8) \)
Sustituir \( x = 8 \) en la función \( f(x)=\sqrt[3]{x - 8} \).
\[
f(8)=\sqrt[3]{8 - 8}=\sqrt[3]{0}
\]
Como la raíz cúbica de 0 es 0, entonces \( f(8) = 0 \).
Step2: Calcular \( f(-117) \)
Sustituir \( x = -117 \) en la función \( f(x)=\sqrt[3]{x - 8} \).
\[
f(-117)=\sqrt[3]{-117 - 8}=\sqrt[3]{-125}
\]
La raíz cúbica de -125 es -5, ya que \( (-5)^3=-125 \), entonces \( f(-117)=-5 \).
