Question

How do you solve this: 2y^2=x+4

Answer 1

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 =
`(x + 4)/(2)` ----> take the square root of both sides

y =
`\sqrt{(x+ 4)/(2)}`

Now you have the equation solved for the y variable and can graph it.
