I need to fill in the blanks to make a true statement out of the following:

[FONT="]n2 + log2n ϵΘ (n2) because ___ * n2 ≤ n2 + log2n ≤ ____ * n2 for all n ≥ ____[/FONT]

I barely know how to approach this, but one question I have would be, how do you put [FONT="]log2 [/FONT]into a graphing calculator? I have a TI-83 Plus. (Yes, it's not the best). I think I might have an idea of what to do if I knew how to put it into the calculator. But I could still use a lot of help on this one. Thanks in advance!

PS, this didn't post right. All of the "n2"s are supposed to be n^2, (n squared), and the "log2n"s are supposed to be log sub 2 times n. Thanks.
