No dice? Question unclear or just stupid?

So I understand that a monotonic transformation preserves the order of a function, but I was wondering: could you perform a transformation by multiplying by a variable? For example the formula: U = (XY) - (XY/(Z+1)) Is it an acceptable monotonic transformation to multiply the whole...

Although, I've been reading that extreme values can occur at endpoints, stationary points, and singular points. So obviously this function has some singular points, but I do not know enough to go any further. Could there be a max at the asymptotes?

I'm thinking you are probably right. On an exam no less :S. Guess I should have known better. Thanks again.

Thanks for the reply, you are making sense to me. I'm still confused as to why I was asked to maximize it, when there are no maximum points?

Homework Statement Seems straightforward enough, Lagrangian optimization Homework Equations Find the max of x^-1 + y^-1 subject to the constraint m=x+y The Attempt at a Solution At first I thought no problems, x*=y*=m/2, however: Using the Lagrangian formula yields...
