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

Multiple Choice

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

A) Yes
B) $\mathrm { No }$
