Question 49

Multiple Choice

f(x) =4x4;g(x) =2x2f ( x ) = - 4 x ^ { 4 } ; g ( x ) = - 2 x ^ { 2 }
Find (fg) (x) .\left( \frac { f } { g } \right) ( x ) .


A) (fg) (x) =8x6, where x0\left( \frac { \mathrm { f } } { \mathrm { g } } \right) ( \mathrm { x } ) = 8 \mathrm { x } ^ { 6 } , \text { where } \mathrm { x } \neq 0
B) (fg) (x) =2x2, where x0\left( \frac { f } { g } \right) ( x ) = 2 x ^ { 2 } , \text { where } x \neq 0
C) (fg) (x) =2x2, where x0\left( \frac { f } { g } \right) ( x ) = - 2 x ^ { 2 } , \text { where } x \neq 0
D) (fg) (x) =2x4, where x0\left( \frac { f } { g } \right) ( x ) = 2 x ^ { 4 } , \text { where } x \neq 0
