Quiz 3.8
Question: Solve the following inequality. You may express your answer as an inequality or you may use interval notation. Write an inequality like x  ≤  3 OR x  ≥  5 as x<=3 or x>=5. Write a solution composed of two intervals like x is in (–∞, 5] or x is in [7, ∞) as (-infinity,5] or [7,infinity). If there is no solution, write no solution, and if all real numbers satisfy the inequality, then write all real numbers.
|x + 4| – 4  ≥  1

 
     
  Variations:
|x – 2| – 2  <  –1

 
     
   
|x + 2| + 3  >  1

 
     
   
|x – 4| + 3  ≤  2

 
     
   
|x + 2| + 1  ≤  1

 
     
   
|x + 4| + 1  >  1
