Question 551222
Use |x| not [x].


All x between -4 and 4 (non-inclusive), so -4 < x < 4.


For the other inequality, |x| > 4, either x is greater than 4 or x is less than -4 (since the "distance" from zero is greater than 4) so x > 4 or x < -4.


Update: I didn't conjecture anything. Also, you posted some question about baseball specifications and there is not enough information to solve it since you didn't provide any table or chart. (Hint: Absolute value is never a negative number (it measures "distance" from zero, and distance is always non-negative)
