What is the concavity of this function?

X+x2/3? I got the second derivative, and I. Did not gvet a value. Does this function not have concavity?

Note:2/3 is an exponent.

Hi realism877! :smile:

Note:2/3 is an exponent.

Note the x2 and x2 buttons in the edit screen. They allow you to write subscripts/supscripts.

Anyway, you calculated the second derivative and you "don't get a value". What do you mean with that?? What is the second derivative of the function?

Do you mean that you don't find a point where the second derivative is 0? Well, that's certainly true.
