Answer:
Attention! the "x" variable was missing in your typed question, but I am assuming that the actual function was defined by:

Table:
![\left[\begin{array}{cc}x & y\\-12&15\\-6&11\\3&5\\15&-3\end{array}\right]](https://img.qammunity.org/2020/formulas/mathematics/middle-school/kllbxsgup03al76uxfpig5codqu0eq6smq.png)
Explanation:
In order to complete the requested table, we need to evaluate "y" for the four given values of the "x" variable in the Domain: {-12. -6, 3, 15}
Evaluation:




The table therefore will be:
![\left[\begin{array}{cc}x & y\\-12&15\\-6&11\\3&5\\15&-3\end{array}\right]](https://img.qammunity.org/2020/formulas/mathematics/middle-school/kllbxsgup03al76uxfpig5codqu0eq6smq.png)
