\[f(x)=(x-7)(3x+1)(x+4)\]

do you need to simplify?

You actually have 2 unknowns here. Is there more to this question?

Oh no its a sign chart that you make to solve it with lol but okay(:

I got 7, -1/3 and -4 ....but the -1/3 doesnt look right to me:/

Thats correct! So that solves our zero.

Now what do you think the answer will be for the negative?

ummm im a little confused now :(

I don't know how to make a sign chart. I don't ever remember having to do that.

Oh okay I got it now(:

WAITTTTTTT!!!!!!
