Either enter x^3^-1 directly or define a little function with a command
such as
         define cr(u)=u^3^-1  (or you could use x here, too)

Be sure you use the _negation_ (-) key and not the _subtract_ key in both
cases.  Once you have defined a function you can enter things like 1+cr(8)
or Graph cr(x), but the function only exists inside your current folder.
Tradeoffs, tradeoffs...
