hey everyone:
Use a definition to work forward from each of the following statements.
b. for functions f anf g the function f + g is convex, where f + g is the function whoes value at any point x is f(x) + g(x).
Definition of a convex function: http://en.wikipedia.org/wiki/Convex_function (the equation)
So guys, I'm really stumped, what are we asked to do here. I have a hunch that we have to add g(x) of a convex function to the f(x) of one, but we only have the function of f to work with, and also in the definition we get a y variable, that was not even mentioned in the question... what is up with that. If someone can at least guide me in the right direction, i'd be eternally grateful
