WebAug 29, 2024 · The first order condition for convexity of a function states that: For a convex function f over a convex domain: f ( y) ≥ f ( x) + ∇ f ( x) T ( y − x). Actually this is an iff, but lets leave the other side here. There are plenty of proofs for this online, with an example appearing here for reference. All proofs I've seen do the same: http://www.econ.ucla.edu/sboard/teaching/econ11_09/econ11_09_slides1.pdf
