Use synthetic division to determine whether the number k is an upper or lower bound (as specified) for the real zeros of the function f.

k = -1; $f(x) = 4x^3 - 2x^2 + 2x + 4$; Lower bound?

Yes
No

synthetic division

-1 |   4   -2   2    4
             -4   6    -8
        ----------------
        4   -6   8   -4

remainder is negative so yes its a Lower Bound

Thank you so much! Is that all lower bound is? The remainder is negative?
