I think what Bubba was referring was to Happy_Reaper's reply. Fixed points, not intersections.
It is obvious that both functions intersect at the fixed point since both functions cancel each other.Originally Posted by Bubba

From now on a large part of your life will be spent finding and correcting your own mistakes.
And if you are lucky and land yourself a good job, a whole lot more time will be spent finding and correcting other people's mistakes.
That has to be good, no?

Heh. I agree .... what was that quote ...

This always happens whenever you have a linear relationship of the form f(x) = mx + b, where m != 1. You'll find that f(x) = x when x = b/(1-m).
What you have are two linear functions that are inverses of each other (by design, since converting from Fahrenheit to Celcius to Fahrenheit should give you the same temperature), and since one has a fixed point, the inverse must have the same fixed point.
You'll find the same thing with, say, g(x) = 2x + 3 and h(x) = (1/2)(x-3).
Every non-constant linear function has an inverse function, and they'll always have the same effect.
