Answer:


Step-by-step explanation:

Given,

[tex]f(x)=-x^{2} +6x-1\\g(x)=3x^{2} -4x-1[/tex]

we know,

(f-g)(x)=f(x)-g(x)

So, here we get

(f-g)(x)

=f(x)-g(x)

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

=[tex]-x^{2} +6x-1-3x^{2} +4x+1[/tex]

=[tex]-x^{2}-3x^{2} +6x+4x-1+1[/tex]

=[tex]-4x^{2} +10x[/tex]

So, the answer is

[tex]-4x^{2} +10x[/tex]

Answer:

(f-g)(x) = -4x^2 + 10x - 2

Step-by-step explanation:

Writing f(x) first and then writing g(x) beneath it may make this problem a bit easier to understand:

 f(x)=    -x^2+6x -1

-g(x) = -3x^2+4x -1

-----------------------------

(f-g)(x) = -4x^2 + 10x - 2
