x(x+3)^2

I understand its a cubic function.

Anyone care to help me with solving and graphing it? thanks.

**Reiny**, Monday, November 21, 2011 at 3:02pmYOu 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.
