You can find "y" so:
[tex]2y = 6 - 4x^{2} [/tex]
and
[tex]y = 3 - 2 {x}^{2} [/tex]
then you can build a table, where you assign a value to "X" and replace it in the last :
X | Y
-2 | -5
-1 | 1
0 | 3
1 | 1
2 | -5

In the grafich it seens like a parabola.
It was how i ll resolve that, idk if it is correct.
