Answer:
y = 0
Step-by-step explanation:
Given a rational function
f(x) = [tex]\frac{g(x)}{h(x)}[/tex]
If the degree of g(x) < degree of h(x), then
y → 0 as x → ± ∞
Thus y= 0 ( the x- axis ) is the horizontal asymptote
For the given rational function
The numerator is of degree 2 while the denominator is of degree 3
Thus
y = 0 is the horizontal asymptote of r(x)
