For what values of x the following is true. 1/x^2<=-1 A)1 B)-1 C)2 D)-2 E)None
The values of x that satisfy `1/x^2 <= -1` have to be determined.
The square of any number, positive or negative is a positive number. For `x^2 >= 0` , `1/x^2` is also a positive number.
For none of the given values of x is the condition `1/x^2 <= -1` satisfied.
The correct option is E.
