    So f(x) is x+2 correct?

    You got it confused, the function is f(x)=x+2 So, when x=1, you write the function as f(1)=1+2, you then ignore the f(x), or you can simply say that what's 1+2. Then, you got 3, Now you can rewrite it back as f(1)=3

    The "x" in f(x) is simply "states" that what value of "x" you are substituting into.
