    In an F of X problem all you do is evaluate the problem replacing the x with the number inside of the parenthesis. So, for this it would be f(2)=2(2) + 1

    Work that out...Forget the left side work out the right side...you know what x is but now you need to know the combination of F of X

    It is easy and sometimes fun when you get the hang of it. You are in algebra one I can tell but when you get into algebra two you will start graphing them which is much more difficult.

    It is like this...(blank)=a+1 if a = 1...the answer would be found by replacing the in the right side of the problem with 1
