Hello. I have a calculus problem that goes as follows:
Is it possible to find a function for which it is true that, for all x > 0 and y > 0, fx > 0 and fy < 0, and f (x,y) > 0? If so, give an example. If not, why not?
I'm not sure how to go about solving this. I can't think of an example to make it true, but I don't know how to prove it false. Can someone please help me?
