Question 271681
Each of the following inequalities is true for some values of x EXCEPT

A   x < x^2 < x^3

B   x < x^3 < x^2

C   x^2 < x^3 < x

D   x^3 < x < x^2

E   x^3 < x^2 < x 

<pre>

A is true for x=2 

B is true when x=-.5 

D is true for x=-2 

E is true for x= .5

So the only one left is C.  

The cube of a number is never between the number and its square.
