Answer 2

The answer is the second one on the list

Explanation:

First switch y with x to get x=2y^2-4

Then add four to the x in order to isolate the 2y^2

Then you have x+4=2y^2

Then divide both sides by 2

Now you will have x+4/2=y^2

Now square root both sides in order to get rid of the squared y

Now you should have y equals the square root of x+4/2

Hope this makes sense and helps. Its hard to explain!
