Dear jauneet

y= 1/1-|x|^2

we can write  |x|2 =x2

because x2 is positive for all x

for this function check the critical point

here +1 and -1 is a critical point because graph tends to infinity at these points


 find  Lt x→1{1/1-x2 }


and  Lt x→1{1/1-x2 }


and  Lt x→-1{1/1-x2 }


and  Lt x→-1{1/1-x2 }


and clearly at x=0 ,y=1

now draw the graph
