Answer
\begin{align*}
&\text{A Function
}\\&\text{Domain: }\{
-10,-6,5,6,10
\}\\&\text{Range: }\{
2,4,3,7
\}
\end{align*}
Work Step by Step
In the given set of ordered pairs, \begin{align*}\left\{
(10,2), (-10,2), (6,4), (5,3), (-6,7)
\right\}\end{align*} the first coordinates are all unique. Hence the given set defines a function.
The domain is the set of all first coordinates, while the range is the set of all second coordinates.
Hence, the given set has the following characteristics:
\begin{align*}
&\text{A Function
}\\&\text{Domain: }\{
-10,-6,5,6,10
\}\\&\text{Range: }\{
2,4,3,7
\}
.\end{align*}
