A. False. The range of
f(x) is the set of values it can produce. In the table,
f(x) produces values from
0 to
3. However, the range of all real numbers is all rational numbers, basically from
-\infty to
\infty, not just a few numbers in-between. So, the range of
f(x) is not all real numbers.

B. True. Looking at the table, when
x=-3,
f(x)=2. This is another way of saying that
f(-3)=2, which is what B is saying.

C. True. The domain of
f(x) is the set of values of
x that produce some output in
f(x). Looking at the table, all of the
x values listed on it are in the set
\{-5, -3, 0, 2, 6, 7, 9, 10, 13\}, which is what C is saying.

D. False. Looking at the table, when
x=0,
f(x)=3. This is another way of saying that
f(0)=3, which is not what B is saying.
