It's B.( f - g) (x) -5x2 - x- 4

Hey there!

[tex](f-g)(x)[/tex] would be the same as [tex]f(x)-g(x)[/tex]

We know the following information:

[tex]f(x)=-4x^2-6x-1[/tex]

[tex]g(x)=-x^2-5x+3[/tex]

Now, let's calculate for [tex](f-g)(x)[/tex]

[tex](f-g)(x)[/tex]

= [tex]f(x)-g(x)[/tex]

= [tex](-4x^2-6x-1)-(-x^2-5x+3)[/tex]

= [tex]-3x^2-x-4[/tex]

Your answer is the last choice, or option D.

Have an awesome day! :)
