Use the graph to write the function as a piecewise

• $-x+4;\ x\le0$
  $x+4;\ \ x>0$
  

• $x+4;\ x\le4$
  

  
  $x+4;\ x>4$
  

• $4x+1;\ x\le4$
  

  
  $-4x+1;\ x>4$
  

• $-x;\ \ x>0$
  

  
  $x;\ \ x\le0$
  

Use the graph to write the function as piecewise

• $-x+3;\ \ x\le3$

• $x-1;\ \ x\le3$
  

  
  $x+7;\ \ x>3$
  

• $x+1;\ \ x\le-4$
  

  
  $x+7;\ \ x>-4$
  

• 
  

  $-x-1;\ \ x\le-4$
