Among other things, you'll need to replace _Real with _?NumberQ. 3
does not have a head of Real.
Also, because Plot has Attributes[Plot] = {HoldAll,...}, you'll need
to wrap Epilog->{g...} in Evaluate to make sure g gets replaced by the
correct value.
At this point, if you put //Trace after each version of the Plot
command, you can see that both end up evaluating the same thing. And
both do produce the correct plot.
Hope this helps.
