How to determine f(x) and g(x) for area between curves? So if I'm trying to figure out the area between two curves, I understand that the formula is: ∫ f(x) − g(x)dx But without them telling me which is f(x) and g(x), how do I tell which function is being subtracted and which is being subtracted from? For example I have the equations: x=2y2 and x=4+y2

Question
How to determine f(x) and g(x) for area between curves?
So if I'm trying to figure out the area between two curves, I understand that the formula is: ∫ f(x) − g(x)dx
But without them telling me which is f(x) and g(x), how do I tell which function is being subtracted and which is being subtracted from?
For example I have the equations:
x=2y2 and x=4+y2
In this case my textbooks shows that the second equation is g(x) and the first is f(x), but why?
