Question

I'm wondering. If y(x)=K for all integer x. Is y(x) also considered as bounded?

Answer 1

K is a constant.

Answer 2

y(x) is bounded if\[y(x)\le M\]for all x in your domain and where M some constant.
You have this condition:\[y(x)=K \rightarrow y(x)\le K\] (you can choose your constant M to be K).

Answer 3

That is, y(x) is bounded for all x an integer.

Answer 4

thanks..

Answer 5

No probs.
