We have the identity (f+g)(x) = f(x) + g(x). It stands to reason that (f-g)(x) = f(x) - g(x).

For this example,

(f-g)(x) = (x^2 + 2x - 6) - (x + 5)

(f-g)(x) = x^2 + 2x - x - 6 - 5

(f-g)(x) = x^2 +x -11

Let me know if that makes sense or you have a question about a different identity!

"In the space provided"----I don't know what to do with that...

The difference between 2 functions is nothing more that subtracting one from the other:

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

x^2 + 2x − 6 - ( x + 5)

x^2 + 2x − 6 - x - 5

x^2 - x - 11
