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??
$\displaystyle
f(x)=(x+2)^{\frac{2}{3}}-(x-2)^{\frac{2}{3}}\\
$
$\displaystyle
m=lim_{x->\infty}\frac{f(x)}{x}=0\\
$
$\displaystyle
n=lim_{x->\infty}(f(x)-mx)=?\\
$
