comment Finding the inflection point for a function
If the signs of $ f'' $ to the left and to the right were different (or equal) I could use the test of the second derivative to assert something about the concavity, but as far as I understand this is not the case (I can't imply anything about the signs of $ f'' $ from $ f' $). What am I missing here?
