Answer 2

Why are you just reposting? You still have shown no work of your own. Again, I ask, what kinds of functions are NOT constant multiples of "x".

Answer 3

I don't know.

Answer 4

Seriously? Is 2x a constant multiple of x? Is x^2 a constant multiple of x? Is e^x a constant multiple of x? You have to get up to speed. This will not do.
