Answer

Explanation:

Step1: Find the horizontal asymptote

For a rational function (f(x)=\frac{a_nx^n+\cdots+a_0}{b_mx^m+\cdots + b_0}), if (n = m), the horizontal asymptote is (y=\frac{a_n}{b_m}). For (f(x)=\frac{3x^{2}+1}{x^{2}-9}), here (n = 2), (m = 2), (a_n=3), (b_m = 1).

Step2: Calculate the value of the horizontal asymptote

Using the formula (y=\frac{a_n}{b_m}), we substitute (a_n = 3) and (b_m=1). So (y=\frac{3}{1}=3).

Answer:

A. The function has one horizontal asymptote, (y = 3).
