Hi Sergio,
it is because Mathematica by default tries to select a region of most 
interest in a plot.
Evaluate this to see that your function works properly:

Plot[
  Evaluate[f[x]], 
  {x,Xa,Xb},
  PlotRange->All, (*this turns off the mentioned default*)
  Frame->{True,True,False,False},
  Axes->False
  (*the Axes and Frame statements make it easier to see that f=0 for 
    x>1.5*)
]


For more details about this feature see Tom Wickham-Jones' "Mathematica 
Graphics", Telos, 1994.
Cheers,
Peter
