I have a question on a tutorial involving using the definition to prove a function is continuous. I missed the lectures on this so im not sure about it...
Let and b > -3
Prove, from the definition, that f(y) is continuous at y = b.
[hint use the identity ]
Prove, from the definition, that f(y) is continuous from the right at y = -3
any help appreciated.

Let , choose some to be determines such that when . Upper bound for given that so let us say . So by triangle inequality, . Now consider . We have:
{ 1, / }
sorry but im not that great at the math equation thing yet so the last bit is a bit muddled. And somehow my font has gone red... weird...
After this (if its right) i dont really know how to end it.
