Where do I even start

[glad raptor]

Im not looking for a step by step solution but more what prerequisite knowledge do I need? My professor taught proof by induction and sequence limits before this which I understand both, but I am completely dumbfounded here

Those are called epsilon-delta limit definitions so it's just asking you for the correct choice of the form

You can either read up on that or I can try and explain whatever you prefer

Im not home right now so when I’m back I’ll try to read on it by my own just to try, but thank u so much
