let f(x)=-2x+4 and g(x)=-6x-7. find f(x)-g(x). Please show work, I don't get it. The other problem I don't get is f(x)=3x-7 and g(x)=-2x-6. Find (f o g)(4). I don't understand any of this, finished the other questions.

If you want to find f(x)-g(x), write f(x) first and g(x) underneath it, and then subtract, column by column.

let f(x)=-2x+4 and g(x)=-6x-7. find f(x)-g(x).

         f(x)=-2x+4
       - g(x)=-6x-7
     -------------\

Combine each column.
