Indicate whether the following assertions are true or false, and give a justification.

If you are justifying the positive direction, give choices of n$0$ and C$.$ For big$-\backslash$Theta $,$ make sure to justify both big$-$O and big$-\backslash$Omega $,$ or big$-$O in both directions.

If you are justifying the negative direction, indicate which term$($s$)$ can$$t work because one is guaranteed to grow faster or slower than the other.
