1. The problem statement, all variables and given/known data http://s14.postimg.org/an6f4t2ht/Untitled.png 2. Relevant equations 3. The attempt at a solution I'm not sure what they want me to do on the last part. I tried some googling and looking in my textbooks but I didn't find any examples. It seems to me like the function goes to infinity if it's unstable as x -> inf. Can somebody explain to me what exactly they want me to do?
