f(x) =Function of X or (two variables)
y= a variable
The differnce of f(x) and y depends on the problem you are dealing with. X & Y could be variables on a graph or they could be given numbers to plug in and solve for. The differnce in x and y variable are just the letter that you are solving for unless there is an equation. If you have a math book it should go into more detail.

Not much, in a math class... f(x) just refers to the value of something that is a function of x (dependent on the value of x), while y refers to a y coordinate on a graph of x versus y. Usually we graph f(x) on the y axis so they are the exact same thing.

f(x) means the value of the function f at x.
y, by itself, is just the name of a variable. It needn't have anything to do with f.
The equality y = f(x) is a condition on the two variables, x and y (for example, it can be a law of nature in science).

Nothing. Just a different way of defining a function.
f(x) = y
