Nah not step by step, here's something to think about...

For you can multiply numerator and denominator by and get . For limit as , this becomes a limit of the form , which means you can apply L'Hopital rule.

For the second limit, divide numerator and denominator by . Find the limit of the leftover expression.

For Q2, determine limits as and , what are the the axes intercepts? Does this function have a certain max/min?

For Q3, use a substitution... I'll let you think of what it should be.

and for Q4 we can deal with it if you get there.
