$f ( x ) = 3 x ^ { 3 } - 1 ; g ( x ) = 3 x ^ { 2 } - 1$
Find $( f \cdot g ) ( x )$
A) $( f \cdot g ) ( x ) = 9 x ^ { 6 } - 3 x ^ { 3 } - 3 x ^ { 2 } + 1$
B) $( f \cdot g ) ( x ) = 3 x ^ { 3 } + 3 x ^ { 2 } + 1$
C) $( f \cdot g ) ( x ) = - 9 x ^ { 5 } - 3 x ^ { 3 } - 3 x ^ { 2 } + 1$
D) $( f \cdot g ) ( x ) = 9 x ^ { 5 } - 3 x ^ { 3 } - 3 x ^ { 2 } + 1$

The Answer is D

f(x)=3x3−1;g(x)=3x2−1f ( x ) = 3 x ^ { 3 } - 1 ; g ( x ) = 3 x ^ { 2 } - 1f(x)=3x3−1;g(x)=3x2−1

$f ( x ) = 3 x ^ { 3 } - 1 ; g ( x ) = 3 x ^ { 2 } - 1$
