If given f(x) = _4x _ 2 and g(x) = 2x, what is (f ‡ g)(x)?

a.
(f ‡ g)(x) = _6x _ 4
b.
(f ‡ g)(x) = _8x2 _ 4x
c.
(f ‡ g)(x) = _6x _ 2
d.
(f ‡ g)(x) = _16x2 _ 4x

I hope this helps you

f (x).g (x)=(-4x-2).2x

f (x).g (x)=-4x.2x-2.2x

f (x).g (x)= -8x^2-4x

There are two equations given in the question and these two equations have to be multiplied. 
f(x) = _4x _ 2
And
g(x) = 2x
Then
f (x).g (x) = (-4x-2).2x
f (x).g (x) = -4x.2x - 2.2x
f (x).g (x) = -8x^2 - 4x

From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the second option or option "B".
