Question

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 = 4; f(x) = 2x3 - 2x2 - 3x - 5; Lower bound?

Answer 1

\[k=4; f(x)=2x^3-2x^2-3x-5\]

Answer 2

I know synthetic division, but how do I use it to find if the equation is upper or lower bound...?
