determine where it is concave up and where it is concave down. Also find all the inflection points, i.e. points where the second derivative changes sign (i.e. goes from being positive to being negative, or vice versa):
f(z) = 3z^2− 1/(z^2 )

Step 1


Step 2

Finding its first and second derivative by differentiating with respect to z, we get 

Step 3

Now, finding the points where second de...
