Hey All:

I am not sure where to post something like this.

I have encountered something I am not familiar with too well.

This is part of

determine rather this is true or not:

$\displaystyle f(n)\in {\Theta}(n^{3})$

$\displaystyle f(n)\in {\Omega}(n^{2})$

What does this stuff represent?.

Anyone have an idea?.

The theta is the asymptotic tight bound and the Omega is the asymptotic lower bound.
