Find the inverse of the function y=2x^2-4

Answer:
The answer is the second one on the list
Step-by-step 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!
