Curve Sketching

[wolfy-wolfy]

I am in 11th grade and we are learning about curve sketching. I am stuck on a question.


I want to sketch y=x^2lnx. I know the basic shape of the graph, but I do not know how to find the concavities and where they are.


Can someone please help me?

I do not know how to find the concavities and where they are.

Has your class not covered the techniques (Second Derivative Test, etc) for finding intervals of concavity and points of inflection? If not, then try online lessons, such as here. If so (or, if not, then after you've studied at least two lessons from the listing at the link), then what techniques have you chosen to apply, and where are you stuck in the process?

Please be complete. Thank you!
