I need to find the x and y intercepts of this:

f(x) = x^3 - 4x

The y-intercept is just zero right? So how about the x's? I haven't done this in a while. Do you just factor this or do you do something else? I know it's easy.. but I'm having a major brain fade here. (Headbang) I'm guessing the x is on -4 and 4?

Edit: I think I got it. x-intercepts are on (-2,0) and (2,0)?
