Answer 2

Where it's defined depends on your environment. The code is inside a compiled C standard library somewhere.

Its "definition" is in the source code for your c standard library distribution. One such distribution is eglibc. This is browsable online, or in a source distribution:

w_pow.c

math_private.h

Short answer: In the C standard library source code.
