We define a function f(x) such that f(11)=34, and if there exists an integer a such that f(a)=b, then f(b) is defined and f(b)=3b+1 if b is odd f(b)=b/2 if b is even
What is the smallest possible number of integers in the domain of f?
Never mind, hectictar posted a solution to another guy's post. Sorry!
