(E) II and III only 3 12. The figure to the right depicts the graph of the equation y = 1/x. Q y=1/x Points P and Q are given as points of intersection of a tangent line with the x- and y-axes, respectively. If P is moving to the right at 5 mm/sec, how fast is Q moving down when P is 2 mm from the y-axis? P X 2 (A) 1 mm/sec (B) 2 mm/sec (C) 3 mm/sec (D) 4 mm/sec (E) 5 mm/sec
