Given that busybox may eventually include an operating system kernel
and a C library of its own :->, but will certainly never
(substantially) work with a different kernel than Linux, why not

mountpoint()
{
        cut -d' ' -f2 /proc/mounts | grep -q "$1"
}

plus a set of similar small shell functions that print the other
information, insofar requested?
