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

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