Use Synthetic Division to Determine Whether the Number K Is $\mathrm { k } = - 1 ; \mathrm { f } ( \mathrm { x } ) = 4 \mathrm { x } ^ { 3 } + 5 \mathrm { x } ^ { 2 } - 4 \mathrm { x } - 3$

question 155

True/False

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.
- $\mathrm { k } = - 1 ; \mathrm { f } ( \mathrm { x } ) = 4 \mathrm { x } ^ { 3 } + 5 \mathrm { x } ^ { 2 } - 4 \mathrm { x } - 3$ ; Lower bound?
