## vertiacal assimptote question..

i need to fin the vertical asimptote of this function
the m is 0 because the denominator has a higher power then the numenator.
but i got stuck on n??
$
f(x)=(x+2)^{\frac{2}{3}}-(x-2)^{\frac{2}{3}}\\
$

$
m=lim_{x->\infty}\frac{f(x)}{x}=0\\
$

$
n=lim_{x->\infty}(f(x)-mx)=?\\
$
