how 2 draw graph of 1/1-|x|^2
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
now
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
