I need help with |x+4| greater than or equal to -1
==========
|x+4| >= -1
Case 1:
x+4 >= -1
x >= -5
=============
Case 2:
-(x+4) >= -1
-x -4 >= -1
-x >= 3
0 >= x+3
-3 >= x
x <= -3
===========
-5 <= x <= -3
---------------
Peculiar tho, because any absolute value must be >= zero.

absolute value of any expression must be greater than or equal to 0.
therefore abs(x+4) >= 0
this is true for any value of x.
therefore abs(x+4) >= -1 is true for all values of x.
