How do you test the critical points of a function if the second derivaive test quals zero? I know you have to use higher order tests, but I don't know what they are... Can anyone help?

    if the second derivative test is zero for the same values you found in the 1st derivative, you most likely have inflection points that are giving you a false reading in your 1st.

    If you can get your derivative into a fully factored form it's pretty easy to see if you have a min/max or inflection point.
