Since you do not explain what you mean by "...does not really look exactly
line the plot given by Microsoft
EXcel", it is rather difficult to answer your question. However, I would
guess that it has something to do with the fact that Mathematica does not plot all
of the curve f[x]. Include the option PlotRange->All, and you will see  that
part of the curve near x=0. Also, you can use PlotPoints->50 to get a
slightly smoother plot of the curve, but this is a small change.
