It has been a long time since I plotted anything on the MMA program. 

I would however like to know why this is not plotting correctly, The
math for this is completely sound by the way.

I want to have MMA plot the following:

Plot[{-x^3, -x^(1/3), x}, {x, -10, 10}]

I get the following errors for this:
Plot::plnr : -x^(1/3) is not a machine-size number at x = -10
"       "       "      "  "  "     "   " "    "     " x = -9.18866
"       "       "      "  "  "     "   " "    "     " x = -8.30382

I have tried to expand the restrict values to no end. Any information
would be helpful in this matter.

Note the the following does graph correctly:
and only part of the graph for the third.

Do not understand why it is doing this
please send information to email address listed below I will get it

Thanks for any help in this!!
