Find the local extrema of abs(x-1/x+1)

Hello baha

there are two ways to solve this problem one with graph and other with simple ..calculation..now let me first tell you by calculation

So i am solving it with graph which is quite easier one...

Y = | (x-1)/(x+1) |  =  | (x -2 + 1)/(x+1) | = | 1 - 2/(x+1) | 

Given figure is the graph of this function

From the graph it is clearly visible that function has minimum value at x= 1 ..hence this is local minima ..and at +-infinty it has maxima..which is global maxima...
