Redefine the function which is given by
f(x)= |x-1|+|1+x| , -2?x?2

Hi,fx= x-1+x+1 where -2x 2 x-1=x-1 if x-1 0-x+1  if x-1 0=x-1 if x1 -x+1  if x<1 x+1=x+1 if x+1 0-x-1  if x+1 0=x+1 if x-1 -x-1  if x<-1 when -2x -1 , we get x-1+x+1=-x+1-x-1= -2x when -1x 1 , we get x-1+x+1=-x+1+x+1= 2when 1x 2 , we get x-1+x+1=x-1+x+1= 2xThus, x-1+x+1=-2x    when -2x -12     when -1x 12x        when  1x 2
