Step-by-step Solution
Find the vertical asymptotes of \( f(x)=\sqrt{\frac{8x-24}{\frac{1}{2}x+5}} \).
Function by following steps:
- step0: Find the vertical asymptotes:
\(f\left(x\right)=\sqrt{\frac{2\left(8x-24\right)}{x+10}}\)
- step1: Evaluate the limit:
\(\lim _{x\rightarrow -10^{-}}\left(\sqrt{\frac{2\left(8x-24\right)}{x+10}}\right)\)
- step2: Rewrite the expression:
\(\sqrt{\lim _{x\rightarrow -10^{-}}\left(\frac{2\left(8x-24\right)}{x+10}\right)}\)
- step3: Calculate:
\(\sqrt{+\infty}\)
- step4: Simplify the root:
\(+\infty\)
- step5: \(x=-10\) is a vertical asymptote\(:\)
\(\begin{align}&x=-10\textrm{ }\textrm{is a vertical asymptote}\end{align}\)
- step6: List all vertical asymptotes of the function:
\(\begin{align}&x=-10\end{align}\)
Find the horizontal asymptotes of \( f(x)=\sqrt{\frac{8x-24}{\frac{1}{2}x+5}} \).
Function by following steps:
- step0: Find the horizontal asymptotes:
\(f\left(x\right)=\sqrt{\frac{2\left(8x-24\right)}{x+10}}\)
- step1: Evaluate the limits \(\lim _{x\rightarrow +\infty}\left(f\left(x\right)\right)\) and \(\lim _{x\rightarrow -\infty}\left(f\left(x\right)\right):\)
\(\begin{align}&\lim _{x\rightarrow +\infty}\left(\sqrt{\frac{2\left(8x-24\right)}{x+10}}\right)\\&\lim _{x\rightarrow -\infty}\left(\sqrt{\frac{2\left(8x-24\right)}{x+10}}\right)\end{align}\)
- step2: Calculate:
\(\begin{align}&4\\&4\end{align}\)
- step3: The finite values are horizontal asymptotes:
\(\begin{align}&f\left(x\right)=4\end{align}\)
Para la función \( f(x)=\sqrt{\frac{8x-24}{\frac{1}{2}x+5}} \):
- El dominio de la función es \( x \neq -10 \) ya que el denominador no puede ser igual a cero.
- La asíntota vertical es \( x=-10 \) ya que el límite de la función cuando \( x \) se acerca a -10 es infinito.
- La asíntota horizontal es \( f(x)=4 \) ya que el límite de la función cuando \( x \) se acerca a infinito es 4.
Quick Answer
El dominio es \( x \neq -10 \). La asíntota vertical es \( x=-10 \). La asíntota horizontal es \( f(x)=4 \).
