simplification is to isolate terms and identify the dominant term. For instance, we might want to expand (n + 1)² to n² +2n+1 to see that n² is the dominant term. i. Use your intuition, the limit test, or algebra to come up with a good guess of a tight bound. For instance, after isolating n² as the dominant term we might guess our polynomial is in (n²). i. Use the limit test or the definitions to prove that your guess is correct. Both methods can provide correct proofs, and its a good idea to practice both methods. Sometimes our guess is incorrect and we need to return to the previous step.

100%
Alice has asked you to help her classify these functions based on their asymptotic
growth rate. That is, she wants you to prove a tight big-Theta bound for each
function by following these steps.
i. Use algebra to simply the function for ease of analysis. Remember the goal of
simplification is to isolate terms and identify the dominant term. For instance,
we might want to expand (n + 1)² to n² +2n+1 to see that n² is the dominant
term.
ii. Use your intuition, the limit test, or algebra to come up with a good guess of a
tight bound. For instance, after isolating n² as the dominant term we might
guess our polynomial is in (n²).
iii. Use the limit test or the definitions to prove that your guess is correct. Both
methods can provide correct proofs, and its a good idea to practice both
methods. Sometimes our guess is incorrect and we need to return to the
previous step.
