Multiple Choice

If f(x) =12x+7f ( x ) = 12 x + 7 and g(x) =x2−5xg ( x ) = x ^ { 2 } - 5 x , find (f⋅g) (x) ( f \cdot g ) ( x )


A) (f⋅g) (x) =12x2−60x+7( f \cdot g ) ( x ) = 12 x ^ { 2 } - 60 x + 7
B) (f⋅g) (x) =x2+17x+7( f \cdot g ) ( x ) = x ^ { 2 } + 17 x + 7
C) (f⋅g) (x) =x2+7x+7( f \cdot g ) ( x ) = x ^ { 2 } + 7 x + 7
D) (f⋅g) (x) =12x3−53x2−35x( f \cdot g ) ( x ) = 12 x ^ { 3 } - 53 x ^ { 2 } - 35 x
