I've seen that but I don't understand how to get that...I don't just want to copy an answer...

anonymous · Answer

Well, you have a zero at x=-1. It has a multiplicity of 1 (odd) so it goes through it. Then you have a zero at x=3. Multiplicity of 2 (even) so it just touches the axis. Then as x gets small you grow really large. Then when x gets large, you grow small. As the picture shows: http://www.wolframalpha.com/input/?i=y%3D-%28x%2B1%29%28x-3%29^2

Can you tell that from the graph? It needs a weird scale to fully see it.

thanks, malevolence19! you're always helpful!

Haha, you're welcome :D But, without calculus, you can't get much better of a sketch then what I offered. You can find asymptotes, LHB, RHB, zeros, and y intercepts without calculus. The rest of it you need calculus to get a well defined sketch.
