Limits problem

Ok tell me if I'm wrong for (k)
I got 1(0) = 0

The answer is indeed 0, but for a different reason. This is the limit of composition g(f(x)), not of product g(x)f(x).

And (l) is undefined right?

Yes. Hopefully you can explain why.

Yes because it's undefined when x approaches -1 for f(x)

No, the behavior of f(x) near x = -1 is irrelevant to this question. What matters is the behavior of f(x) near x = 1. Moreover, it is not enough to say that does not exist. If f(x) were 1 instead of 0, then would still not exist, but would exist.
