We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
x is a fraction (1/2 ..) condition 1 holds true....but I dont get any other number satisfying any of the other two condition...! or my brain has froze...
sst 1 holds true all fractions...
for numbers none of these hold true...
so if x is postive then x must be fraction..
so my pick is one... but what is OA
2x < 1/x when x < Sqrt(2)/2
x^2 < 1/x when x < 1
x^2 < 2x when x < 2
for x < Sqrt(2)/2 we have x^2 < 2x < 1/x
for sqrt(2)/2 < x < 1 we have x^2 < 1/x < 2x
for 1 < x < 2 we have 1/x < x^2 < 2x
for x > 2 we have 1/x < 2x < x^2
so 1. and 2. both work.
This is a good example of why you don't plug in numbers. You would need to pick a number between Sqrt(2)/2 and 1 to get the right answer.
2x < 1/x when x < Sqrt(2)/2 x^2 < 1/x when x < 1 x^2 < 2x when x < 2
for x < Sqrt(2)/2 we have x^2 < 2x < 1/x for sqrt(2)/2 < x < 1 we have x^2 < 1/x < 2x for 1 < x < 2 we have 1/x < x^2 < 2x for x > 2 we have 1/x < 2x < x^2
so 1. and 2. both work.

Could you please explain how did you come up with values for various inequalities
Thanks Joey..!
