How to graph:
x(x+3)^2
I understand its a cubic function.
Anyone care to help me with solving and graphing it? thanks.

YOu meant:
graph y = x(x+3)^2
you know you have a root at x=0 and a double root at x = 3 (it touches at (3,0) )
pick a few more x's and find their matching y's, graph those and you are set.
