This document was created using the gnuplot script

set terminal pstricks
set parametric
set noxtics
set noytics
set noborder
set title "$y^3-y-x=0$"
plot [t=-1.25:1.25] t**3-t , t       notitle lt 1 lw 3, \
                    .5*t   , -2.5    notitle lt 1 lw 3    

along with my fine tuning and added dashed lines, an arrow,
and a wider line width.
