Solution
Solution Steps
To find the vertical asymptotes of a rational function, we need to identify the values of \( x \) that make the denominator zero, as long as these values do not also make the numerator zero (which would indicate a hole instead of an asymptote). For the function \( f(x) = \frac{x^2 - 5x - 24}{x + 3} \), we set the denominator equal to zero and solve for \( x \).
Step 1: Identify the Denominator
To find the vertical asymptotes of the function \( f(x) = \frac{x^2 - 5x - 24}{x + 3} \), we first focus on the denominator, which is \( x + 3 \).
Step 2: Solve for Zero in the Denominator
Set the denominator equal to zero and solve for \( x \):
\[
x + 3 = 0
\]
Solving this equation gives:
\[
x = -3
\]
Step 3: Check the Numerator
Ensure that the value \( x = -3 \) does not also make the numerator zero. The numerator is \( x^2 - 5x - 24 \). Substituting \( x = -3 \) into the numerator:
\[
(-3)^2 - 5(-3) - 24 = 9 + 15 - 24 = 0
\]
Since the numerator is zero when \( x = -3 \), this indicates a hole rather than a vertical asymptote.
Final Answer
There are no vertical asymptotes for the function \( f(x) = \frac{x^2 - 5x - 24}{x + 3} \). Therefore, the answer is "There are no vertical asymptotes." \(\boxed{\text{There are no vertical asymptotes}}\)
