comment Interpretation of polynomial regression output in R
@whuber, why not turn that into an 'official' answer (& maybe develop it a little, perhaps w/ some plots). It is similar to information that exists elsewhere (as you note), but I don't recall having seen it in quite that form / so clear & concise. It's a nice summary of the issue. It would be a shame if it remains buried in a comment.
