stumpted trying to find horizontal asymptote...please help

[roxstar1]

h(x) = x(9-(x^2))^(1/2)

in this problem I have to graph this function using x and y intercepts, points of inflection, relative minimum and maximum, etc. I am stumpted as to how I'm supposed to find the horizontal asymptotes...if this function even has them. Any help would be greatly appreciated.

No denominator so no asymptotes.
The domain is [-3,+3]
x intercepts at -3,0,+3
y intercept at 0
