Need a functional form

Dear All,
I would need a functional form such for f(K) such that:
f(K) is defined for both K=0 and K=infinity;
rate of growth of K is constant;
thanks a lot for your help,
Francesco

Re: Need a functional form

If the rate of growth is constant, than the value of the function is linear. If it is real-valued at infinity, then it must be a constant function with a constant growth of 0.

I don't suspect this is actually what you want, so you must have meant something slightly different...

Re: Need a functional form

Indeed I would need a constant and positive growth rate...

Then your function is of the form y = mx + b for m > 0. But the limit as x approaches infinity is infinite.
