Bruce,
Your pattern for g includes w_Real, but in the plot you passed an Integer
(3) in that position. You could pass 3.0 instead, or you can change the
definition to
g[X_String, w_?NumericQ, f_] :=
Text[Style[X, 12, Bold], {w, f /. {x -> w}}, {0, -2}]
or even
g[X_String, w_, f_] :=
Text[Style[X, 12, Bold], {w, f /. {x -> w}}, {0, -2}]
