Could you please help me understand how you found the lower limit i.e x should be greater than 4/9. I did refer to the previous post as well.But I am not clear with it.
Thanking you in advance.
Could you please help me understand how you got the lower limit as greater than 4/9. I did try going through the previous post on this topic.Still I need more clarity on this.
What about x<-2 in the example from CAT 2005?
Never mind just read the square root function post.
Since it is within a square root sign, it is treated as positive only 🙂

1/[2+1/(4+something positive)]
= 1/[2 + (less than 1/4)]
= 1/[less than 2.25]
= (greater than 1/2.25)
= (> 4/9)
