R help - Apr 2010 - Combining Plots, Plotting functions, Changing scale of axis

Dear R-Helper

First, I would like to integrate different functions (0.066x^(-0.5,0.3,0.7))
into a normal plot.
I tried something with the curve function, but I didn't managed to work it
out.
Furthermore, is it and how is it possible to logarithmic the scales of the
axis?

Thank you very much.
