|x + 2/x | < 3, then x belongs to
(-2,-1) U ( 1,2 )
(-∞, -2 ) U (-1, -1) U ( 2, ∞ )
(-2, 2 )
(-3, 3 )
If 3 < 3 t - 18 ≤ 18, then which one of the following is true?
15 ≤ 2 t+1 ≤ 20
8 ≤ 2 t ≤ 12
8 ≤ t+1 ≤ 13
21≤ 3 t ≤ 24
(x2 + 1 ) ( x -2 ) 2 ( x -3 ) < 0, then x belongs to
( -∞, 2) U (2, 3 )
( -∞, 3)
(2, 3 )
None of these
If x satisfies the inequations 2x - 7 < 11, 3x + 4 < -5, then x lies in the interval
(-∞, -3)
(-∞, 3)
(-∞, 2)
(-∞, ∞)
|2x -3| < | x + 5 |, then x belongs to :
( -3, 5 )
( 5, 9 )
( -2/3, 8 )
( -8, 2/3 )
If a/b < c/d, then
( a/b)2 < (c/d)2
As sinx < x and x < tanx in ( 0,π/2 ), so in the same interval
Sinx < tanx
Sinx > tanx
sin2 x > tan 2 x
|sinx | > |tanx |
If | x | < x , then:
x is a positive real number
x is a non negative real number
There is no x satisfying this inequality
x is a negative real number
If 1/a < 1/b; then
| a | > | b |
a < b
a > b
Log 2 x > 4, then x belongs to
x > 4
x > 16
x > 8
