What is an asymptotically nonnegative function?












0












$begingroup$


I was reading up on the definition of theta- notation and came across this,




The definition of $Theta(g(n))$ requires that every member $f(n) = Theta(g(n))$ be
asymptotically nonnegative, that is, that $f(n)$ be nonnegative whenever $n$ is sufficiently large.




I'm having a little difficulty understanding what this means.

          It means that there is some positive $N$ such that for all $n > N$, we have $f(n) geq 0$.
