Answer 2

Answer:

Step-by-step explanation:

x

|x|

There

it can take only two values:

1 for x>0 --> so we would have: 1<x;

Or -1 for x<0 --> so we would have: −1<x and as we considering the range for which x<0 then completer range would be: −1<x<0.

The same two ranges: −1<x<0 or x>1:

(2) |x|>x. Well this basically tells that x is negative, as if x were positive or zero then |x| would be equal to x. Only one range: x<0, but still insufficient to say whether −1<x<1. (For instance x can be −0.5 or −10)
