Give the answer for the two problems below and justify your answer using the limit theorem and computing the actual limit Saying. "The limit is x because this term dominates the other" is not a valid proof. To clarify. You can use the 'dominant term' argument when you talk about polynomial terms (i2n = O (2^n)?
