Find the domain of the function defined by the table below. Express your answer as a set of numbers.
xx	minus, 9−9	77	minus, 4−4	99	minus, 8−8	minus, 7−7	11
yy	minus, 7−7	minus, 3−3	88	88	22	33	1010


The domain of a function consists of all the \( x \)-values (input values) for which the function is defined. Based on the table provided:

\[
\begin{array}{|c|c|}
\hline
x & y \\
\hline
-9 & -7 \\
7 & -3 \\
-4 & 8 \\
9 & 8 \\
-7 & 2 \\
1 & 3 \\
10 & 10 \\
\hline
\end{array}
\]

The \( x \)-values from the table are: \( -9, 7, -4, 9, -7, 1, 10 \).

So, the domain of the function is:

\[
\{-9, 7, -4, 9, -7, 1, 10\}
\]

Let me know if you need any more details or clarifications.
