Question

Let f(x)=-2x+4 and g(x) =-6x-7. Find f(x) - g(x)

Answer 1

Please anyone help. I have NO idea how to do the f(x), g(X) ect.. questions. Any one? Please.

Answer 2

(-2x+4)-(-6x-7) solve that. and you will get gx - fx

Answer 3

How do I do that? I sound dumb, but honestly I just cant do math on my own without being guided. I know they draw arrows from the 4 to -6x and -2 to -17. So do I subtract those?
