In fact, it is affine along any line of the form $x = y \vec {1} + b$, where $b$ is constant: $f (x) = y + \log\sum_i e^ {b_i}$. EDIT: Richkent wants to know if there are any other lines along which $f$ is affine. The answer is no.

More abstractly, in the language of operad theory, one can consider vector spaces to be algebras over the operad (the infinite direct sum, so only finitely many terms are non-zero; this corresponds to only taking finite sums), which parametrizes linear combinations: the vector for instance corresponds to the linear combination . Similarly, one can consider affine combinations, conical combinations, and convex combinations to correspond to the sub-operads where the terms su…
