Question 32

Multiple Choice

A) $f ^ { t } ( x ) = \frac { \left( 9 + 8 x - x ^ { 2 } \right) } { \left( x ^ { 2 } + 9 \right) ^ { 2 } }$
B) $f ^ { t } ( x ) = \frac { \left( 9 - 8 x - x ^ { 2 } \right) } { \left( x ^ { 2 } + 9 \right) ^ { 2 } }$
C) $f ^ { t} ( x ) = \frac { \left( 9 - 4 x - x ^ { 2 } \right) } { \left( x ^ { 2 } + 9 \right) ^ { 2 } }$
D) $f ^ { t } ( x ) = - \frac { \left( 9 - 8 x - x ^ { 2 } \right) } { \left( x ^ { 2 } + 9 \right) ^ { 2 } }$
E) $f ^ { t } ( x ) = \frac { \left( 9 - 8 x + x ^ { 2 } \right) } { \left( x ^ { 2 } + 9 \right) ^ { 2 } }$
