If you can't directly input the answer into the answer box:

• input 1234 if you think it approaches $$+ \infty$$
• input 4321 if you think it approaches $$- \infty$$
• input 1324 if the limit does not exist and does not approach either infinity.
• input 2016 if still none of the above options best describe the answer.
