Dear all,

How do I plot a graph polynomial to show there is or no local inflection

I am running:

regress y  x  xsquared  xcubic

Is there a command after the regression to get STATA plot a graph?

The results shows there is no local inflection point but it would be nice to
see how the graph looks like.
