    This is a component of a Limit problem I have found to be DNE.

    ah, right, x --> -1, hence my passion to remove x+1 from the denominator.

    This is a solve for limit that I have reached exhaustion upon. I think it is DNE. Lim (x--> -1) of (3x^3 + 1) / (x+1 I can find no result other than indeterminate, using a table shows the val's skate off to infinity in opposite directions as x approaches -1, which both my sketch and your wolf confirms on the chart. Am I missing something?

    The limit on the right does no equal the limit on the left

    Right. Left != Right ----------> Lim DNE

    Thanks for confirming my results - I am slowly building confidence in finding lim.

    you get the above by doing polynomial division (well, wolf to save time and effort). http://www.wolframalpha.com/input/?i=%283x^3+%2B+1%29+%2F+%28x%2B1%29

    Still unable to work past indeterminate result. Okay, I am going to settle finally, finally, finally on DNE. As Regis would want to know, yes, it's my final answer.
