Answer
Explanation:
Step1: Identify degrees of polynomials
For a rational function $f(x)=\frac{a_mx^m+\cdots}{b_nx^n+\cdots}$, in $f(x)=\frac{x^2 + 4}{4x^2-4x - 8}$, the degree of the numerator $m = 2$ and the degree of the denominator $n=2$.
Step2: Recall horizontal - asymptote rule
When $m = n$ for a rational function $y=\frac{a_mx^m+\cdots}{b_nx^n+\cdots}$, the horizontal asymptote is $y=\frac{a_m}{b_n}$. Here $a_m = 1$ (the leading - coefficient of the numerator) and $b_n=4$ (the leading - coefficient of the denominator), so $y=\frac{1}{4}$.
Answer:
$m = n$
