Transcript text: Find the equations of any vertical asymptotes.
\[
f(x)=\frac{x^{2}+1}{\left(x^{2}-1\right)\left(x^{2}-49\right)}
\]
Solution
Solution Steps
To find the vertical asymptotes of the function \( f(x) = \frac{x^2 + 1}{(x^2 - 1)(x^2 - 49)} \), we need to determine the values of \( x \) that make the denominator zero, as these are the points where the function is undefined and may have vertical asymptotes. We will set each factor of the denominator equal to zero and solve for \( x \).
Step 1: Identify the Denominator
The function given is
\[
f(x) = \frac{x^2 + 1}{(x^2 - 1)(x^2 - 49)}
\]
The denominator is \((x^2 - 1)(x^2 - 49)\).
Step 2: Set the Denominator to Zero
To find the vertical asymptotes, we set the denominator equal to zero:
\[
(x^2 - 1)(x^2 - 49) = 0
\]
Step 3: Solve for \(x\)
Solve each factor of the equation separately:
\(x^2 - 1 = 0\)
\[
x^2 = 1 \implies x = \pm 1
\]
\(x^2 - 49 = 0\)
\[
x^2 = 49 \implies x = \pm 7
\]
Final Answer
The vertical asymptotes of the function are at \(x = -7\), \(x = -1\), \(x = 1\), and \(x = 7\).
