Answer :

the absolute value of x is greater than 1/2, meaning that x is either greater than 1/2 or x is less than -1/2 (in this case, even though the numbers are decreasing or getting more negative, their absolute values are greater than 1/2). this is all i can tell you because you didnt give me any graphs. 
|z| > ¹/₂
(z) > ¹/₂      -(z) > ¹/₂
  z > ¹/₂        -z > ¹/₂
                     z > -¹/₂
