Difference between graphs of f(x) and f(x)

It often seems as though it's backwards from what it should be, I had understood f(x) meant to flip x and y, from positive to negative, or vice versa, and f(x) to mean you just make x negative. If you had the points (2,2) you'd make them (2,2) for f(x) and (2,2) for f(x) Is my understanding wrong?

The rest of the title should be graphing.

Ok, that makes more sense.

Assuming that you have the graph of y = f(x), 1. The graph of y = f(x) is the reflection across the xaxis of the graph of y = f(x). 2. The graph of y = f(x) is the reflection across the yaxis of the graph of y = f(x). 3. The graph of y = f(x) is the reflection across the origin (that is, across both axes) of the graph of y = f(x).
