the ones where it looks like this:

......(x - 1)( x - 2)

y=..------------------..................(looks pretty crap)

......(x*2- 9)(x + 4)..................( x*2 = x squared)

well anyway, i know that x cannot equal 3 and -3, and -4... so there are asymatopes... but i dont know what to really do after that...

my teacher did some crap like "when it approaches from 3 on the + side, where does it go? + infinity or - infinity" or some crap like that..........

anyone got any tips on how to do them....
