1. What is an example of f + g + h being bounded while f, g, and h being unbounded

1. As polynomial said, f = 2x, g = -x, h = -x is a solution.
2. f = e^2x, g = e^-x, h = e^-x should work.

Cute transform. I missed the second part of his question.

Remember kids, the exponential function is a group homomorphism between the additive and multiplicative groups of the reals!

Remember kids, the exponential

There's only one?

Yep, exp(x), the one and only.
