maths a-level help

hi this is a sketching a curve graph and the question is sketch the curve its cubic by the way for x(x^2-4)

When y =o, x = 0, -2 and 2. When x =0 y=o

When y =o, x = 0, -2 and 2. When x =0 y=o

sorry how did you get -2 and 2 is it not something like x=0 and x=4

sorry how did you get -2 and 2 is it not something like x=0 and x=4

X^2 -4 =0 so x^2 =4 so x = + and - 2

X^2 -4 =0 so x^2 =4 so x = + and - 2

ooooooOOOOOoooohhhhhh omg im so dumb lol!!!!! :tongue:

Haha it's fine
