The domain of a function is the set of all possible input values, typically represented by the variable $x$, that can be used in the function.

In the table you provided, the $x$-values are listed as:

$x = \{-2, -1, 0, 1\}$

Thus, the domain of the function is the set of all these $x$-values. From the answer choices, the correct domain is:

B. {-2, -1, 0, 1}

Tip: The domain of a function can be visualized as the set of inputs, while the range represents the set of outputs. Always check the function's restrictions (like square roots or denominators) to determine the domain.
