Answer 6

or x+2

Answer 7

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

Answer 8

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