Please, in the future, include a little information with your
question. It is not easy to diagnose problems in the absence of
context: Sage version, Platform (hardware, OS, OS version) at least.
Second, try to explain what "it doesn't work" means. The folks on
this list are pretty good, but their talents typically don't include
the ability to read minds.
As to what might be wrong, I think the problem is that your function
is not one that plot() can handle. sqrt(f) produces (non-real)
complex numbers in the range you are specifying, while plot() expects
real (or, at least, rational) numbers.
