A function of x means that the answers depends on the value of x that is substituted into the function.
For example:
y = x + 1
If x = 1, y = 2
If x = 2, y = 3
and so on.

You must provide a complete equation for the function. Do you mean f(x) = 1.5x + 7.6 or something else?
If you mean: x-2y = 8 then it is y = 0.5x-4.
The expression fxfxf means f(f(x)f(x)), where f(x) is a function of x. This is not equivalent to f cubed (f^3(x)), which would mean f(f(f(x))). In fxfxf, the function f(x) is applied twice to the input x, whereas in f cubed, the function is applied three times. The two expressions are different due to the number of times the function is applied to the input.
f(x) = ...f is the name of the function, and x is the variable. I guess you could say x is the root of the function, because it is what the function relies on.
The only function that can be symmetric about the x-axis is the x-axis itself. For each value of x a function, f(x), can have at most one value for f(x). Otherwise it is a mapping or relationship but not a function.
