Answer :
SOLUTION:
We want to find the domain and range of the relation;
[tex]\left\{\left(6,-4\right)\right\},(4,-4),\left(-1,-4\right)\rbrace[/tex]For this relation, for every bracket, the first elements make up the domain and the second elements make the range.
Thus, the answer is;
[tex]\begin{gathered} Domain:\lbrace6,4,-1\rbrace \\ Range:\lbrace-4\rbrace \end{gathered}[/tex]
