Using the Table command shows the problem
data = Table[f[x], {x, 0, 1, .1}]
{-2.553597742805151*10^608 - 2.186949278296937*10^609 I, -2.546478230057060*10^608 -
2.180851993276173*10^609 I, -2.539378566704049*10^608 - 2.174771707651797*10^609 I,.....
So the data is complex. Now you know the data has complex numbers, the next thing to ask, is how to plot complex data? you can plot the real part and the imaginary part on separate plots. And as the values are so huge, I would normalized it as well first before plotting.
