The domain of a function consists of all the possible input values (or x-coordinates) that the function can take. In the given set of ordered pairs \((9, -2)\), \((6, -10)\), \((-3, 9)\), and \((5, 2)\), the x-coordinates are:
- 9
- 6
- -3
- 5
Therefore, the domain of the function represented by these ordered pairs is the set of x-values:
\[ { 9, 6, -3, 5 } \]
