Solve the Problem $L ( p ) = p ^ { 3 } - 5 p ^ { 2 } + 20$

Multiple Choice

Solve the problem.
-The polynomial function $L ( p ) = p ^ { 3 } - 5 p ^ { 2 } + 20$ gives the rate of gas leakage from a tank as pressure increases in $p$ units from its initial setting. Will an increase of 4 units result in a lower rate of leakage compared to the initial setting?

A) Yes
B) No
