Line 1:

A function <math>f</math> is '''log-concave''', if its [[natural log]] <math>\ln(f(x))</math>, is concave. Every log-concave function is [[concave]], functionhowever isthe log-concavereverse does not necessarily hold.

In parallel, a function is '''log-convex''' if its natural log is convex.
