On page 292 of General Topology by Stephen Willard just before definining h(x), it's stated that g(x)  g_a(x) <= 2/3 for x in A1 \/ B1.
I don't see how he got that nor do I understand how to use it. Could he have meant that g(x)  f(x) <= 2/3 for x in A1 \/ B1?
I think I've a proof of that and it appears useful for the ensuing.
