B is incorrect so it's not the answer...

x^2 - 4x - 3

Step-by-step explanation:

f(x) = x^2 - 6x

g(x) = -2x + 3

(f - g)(x) is the subtraction of the functions, f(x) - g(x)

You need to write it carefully using parentheses for function g(x).

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

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

Now take care of the parentheses by distributing the negative sign to its left. It will change every sign inside the parentheses.

= x^2 - 6x + 2x - 3

= x^2 - 4x - 3
