( x2 + 1 ) (x - 1 ) ( x -2 ) < 0 , then
x < 1 or x > 2
x ∈ ( 1, 2 )
-1 < x
None of these
|2x -3| < | x + 5 |, then x belongs to :
( -3, 5 )
( 5, 9 )
( -2/3, 8 )
( -8, 2/3 )
|3x + 7 | < 5, then x belongs to ______.
( -4, -3 )
( -4, -2/3 )
(-5, 5)
( -5/3, 5/3 )
Log 2x > 4, then x belongs to _______.
x > 4
x > 16
x > 8
If |x| > 5, then
0 < x < 5
x < -5 or x > 5
-5 < x < 5
x > 5
The set of values of x satisfying the inequalities ( x -1 ) ( x -2 ) < 0 and ( 3x - 7 ) ( 2x - 3 ) > 0 is ______.
(1, 2 )
( 2, 7/3 )
( 1, 7/3 )
( 1, 3/2 )
x2 -3 |x| + 2 < 0, then x belongs to ________.
( 1,2 )
( -2, -1 )
( -2, -1 ) U ( 1, 2 )
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
