Can you guys please tell me what I did wrong on this problem? Thanks!!

For the function y = x(x-7)(x + 7),

its y-intercept is (0,0) ??

its x-intercepts are (7,0), (-7,0) ???

When x ->infinity, y-> _________ (negative?)infinity
When x ->-infinity, y-> _________ (positive?) infinity

I do not how to answer your question.
This is almost the same question that we answered before.
Graph the function. What happens when x is very very small (i.e. x negative).
What happens when x is very very large?

Can you tell me if I have my intercepts correct? Thats all I really need to know. Could someone tell me the correct intercepts if I am wrong?

(0,0) would also be an x-intercept
