WebDec 9, 2014 · The rule we need to use is: the composition of a convex, decreasing (or nonincreasing) function with a concave function is convex. That rule is satisfied here by f ( x) = h ( g ( x)), where. h ( x) = 1 / x dom h = ( 0, + ∞) ⊇ S. Note that the restricted domain is important: without it, 1 / x is neither convex nor concave.

I will answer some of your questions. The entries of a Hessian matrix H of f are second partials H i j = ∂ i ∂ j f and it is a standard result in multivariable calculus that ∂ i ∂ j f = ∂ j ∂ i f provided both second partials are continuous functions. In your case, the entries of the Hessian are constants so are continuous functions.
