Homework Statement
Find all relative extrema using the second derivative test for H(x) = x * lnx
Homework Equations
The Attempt at a Solution
H'(x) = (1 * ln x) + (x * 1/x) = lnx + 1
H''(x) = 1/x + 0
Is H''(x) right? Then I am having trouble finding the relative extrema from the second derivative test?
