| Jan 26, 2021 at 21:01 | comment | added | Timothy Chow | @M.H.Hooshmand I found the functional inequality $f(x+y)\ge f(y)(1+x)$ in one of the books mentioned in my earlier comment. Namely, it is Problem 17.11 in Topics in Functional Equations, 2nd edition, by Andreescu, Boreico, Mushkarov, and Nikolov, XYZ Press, 2015. | |
