Hey everybody, I'm new to this forum.

But down to business.

I just started taking an honors math class this year called "Honors Math Analysis".

So anyway... The problem I'm having right now is..

"Use synthetic division to verify the upper and lower bounds of the real zeros ofF"

67.) f(x) = x^4 - 4x^3 + 15

Upper Bound: x = 4 ; Lower Bound: x = -1

I'm pretty confused as to what I'm doing..

She goes really fast and leaves no time at the end of the day to ask questions, and then does not go over the homework the next day for feedback..

This might be the wrong forum.. So I think I'm going to post this in the pre-calc forum.
