Find the horizontal asymptotes. Select the correct choice below and fill in any answer boxes within your choice.

(Type an equation. Use a comma to separate answers as needed.)
B. There are no horizontal asymptotes.
Solution
Solution Steps
Step 1: Finding Horizontal Asymptotes
Since the degree of the numerator, \(m = 2\), is equal to the degree of the denominator, \(n = 2\),
the horizontal asymptote is \(y = 4\), where the leading coefficients of \(P(x)\) and \(Q(x)\) are 4 and 1 respectively.
Step 2: Finding Vertical Asymptotes
Solving \(Q(x) = 0\) gives the potential vertical asymptotes. To ensure they are not holes,
we check if these values also make the numerator zero. The values that do not make the numerator zero are the vertical asymptotes.
The vertical asymptotes are at \(x = -6, 3\).
Final Answer:
The horizontal asymptote is \(y = 4\).
The vertical asymptotes are at \(x = -6, 3\).
