Then [f (n) . g(n)] + h(n) is _______.

a.Ω(n)

b.Ο(n)

c.θ(n)

d.None of these

Okay...thank you Sir

And another thing..can we consider f(n)=1/n for such type of  problems  though it is practically impossible for any program?

yes, we can consider 1/n also and in fact if f(n)=1/n then f(n) is O(1).

Okay thanks :)
