Determine the Percentage Rate of Change of H(p) = $\frac { 4 } { 7 p + 3 }$

Multiple Choice

Determine the percentage rate of change of h(p) = $\frac { 4 } { 7 p + 3 }$ at p = 1 and p = 9.

A) $\frac { h ^ { \prime } ( 1 ) } { h ( 1 ) }$ = 40%, $\frac { h ^ { \prime } ( 9 ) } { h ( 9 ) }$ = 6%
B) $\frac { h ^ { \prime } ( 1 ) } { h ( 1 ) }$ = -70%, $\frac { h ^ { \prime } ( 9 ) } { h ( 9 ) }$ = -11%
C) $$\frac { h ^ { \prime } ( 1 ) } { h ( 1 ) }$$ = -40%, $\frac { h ^ { \prime } ( 9 ) } { h ( 9 ) }$ = -6%
D) $\frac { h ^ { \prime } ( 1 ) } { h ( 1 ) }$ = 70%, $\frac { h ^ { \prime } ( 9 ) } { h ( 9 ) }$ = 11%
