Answer:
12-x*3
Step-by-step explanation:
To solve this for an equation that you can graph, you need to isolate the y variable. In order to do this, follow the order of operations for solving equation to get the equation.
2y^2 = x + 4 ----> divide both sides by 2
y^2 =
----> take the square root of both sides
y = 
Now you have the equation solved for the y variable and can graph it.
