answer
{ input box } submit answer

Explanation:

Step1: Recall domain definition

The domain of a function (defined by a table) is the set of all \( x \)-values (input values) from the table.

Step2: Identify \( x \)-values

From the table, the \( x \)-values are \( 2 \), \( 8 \), and \( -1 \).

Step3: Form the domain set

We collect these \( x \)-values into a set. So the domain is the set containing \( -1 \), \( 2 \), and \( 8 \).

Answer:

\(\{-1, 2, 8\}\)
