A
The domain of h(x) contains all real numbers, the domain of the data set contains
the whole numbers, 0 through 7. The domain of the data set is a subset of the
domain of h(x).
B
The domain of the data set contains all real numbers, the domain of h(x) contains
the real numbers, 0 through 7. The domain of h(x) is a subset of the domain of
the data set.
C
The domain of the data set contains all whole numbers, the domain of h(x) also
contains all whole numbers. The domains are the same set.
D
The domain of the data set contains the whole numbers, 0 through 7; the domain
of h(x) also contains the whole numbers, 0 through 7. The domains are the same
set.
