http://www.wolframalpha.com/input/?i=x%5E3%2F%28x%5E2-9%29 There are obviously going to be breaks as -3 and +3

radar · Answer

the other points get by plug and play.

It needs to have the domain, holes, asymptotes, and zeroes

radar · Answer

x         f(x)                    x           f(x)      
0           0                    -1           1/8
1         -1/8                 -2           8/5
2         -8/5                 -3           undefined
3           undefined        -4           -64/7
4          64/7

Can you not get those from the link?, holes at 3 and -3.

anonymous · Answer

I don't see them in the link.

radar · Answer

The vertical asymptotes are at the points the denominator are zero

radar · Answer

The domain is everywhere else but at the vertical asymptotes.
