Answer:
the table does represent a propor. rela. since y=12x

Step-by-step explanation:
The given equation is
![- \frac{1}{2} {x}^{2} + 2 = 2 {x}^{2} - 8](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%202%20%3D%202%20%7Bx%7D%5E%7B2%7D%20%20-%208)
The graph of the left hand side of this equation is
![y = - \frac{1}{2}{x}^{2} + 2](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%7Bx%7D%5E%7B2%7D%20%20%2B%202)
This quadratic graph has its vertex at (0,2) and turns upside down.
The right hand side of the equation is
![y = 2 {x}^{2} - 8](https://tex.z-dn.net/?f=y%20%3D%202%20%7Bx%7D%5E%7B2%7D%20%20-%208)
This quadratic graph opens upwards and has its vertex at (0,-8).
The two graphs intersects at two points , which are (-2,0) and (2,0).
