Hi pacotomi,
I am not sure whether this problem occurs in other versions of Mathematica.
I try the following command and then it seems that the problem can be solved
by add PlotRange option.
Plot[f[x], {x, 0, 100}, PlotRange -> All]
If any further discovery, welcome to discuss on the board.
Good Luck
ChiaMing
