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

Step-by-step explanation:

We are given the two functions:

$f(x)=-x^2+6x-1\text{ and } g(x)=3x^2-4x-1$

And we want to find:

(f-g)(x)

This is equivalent to:

=f(x)-g(x)

Substitute:

=(-x^2+6x-1)-(3x^2-4x-1)

Distribute:

=-x^2+6x-1+(-3x^2+4x+1)

Rearrange:

=(-x^2-3x^2)+(6x+4x)+(-1+1)

Combine like terms. Hence:

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