In fact, the green function, we still can't tell the difference. You can see the calculation. This is up to three or four decimal places. We're getting awfully close to three now, but we aren't there. So the green function's got there the fastest, is an argument. But the whole point of this is to emphasize the fact that there's an infinite number of functions for which you could make the statement that we made, that the limit of the function as x approaches infinity, in this case, we said that limit is going to be equal to three and I just picked three arbitrarily. This could be true for any, for any function.
