Question 17440
First you might want to find all the zeros or roots of this equation.  That would be 
{{{0=x-x^3}}}
{{{0=x(1-x^2)}}}
{{{0=x(1-x)(1+x) }}}

x= 0, x=1, x= -1


It's best to find ALL the roots first, just to make sure your graph isn't missing something important by looking in too large or too small a window.


Now, graph:

{{{ graph (300,300,-4, 4, -10, 10, x-x^3)}}}
