\( P\left(2 t^{2}, 4 t\right) \) is a point on the parabola \( y^{2}=8 x \) and \( Q(h, k) \) is a point on the tangent at \( P \) and external to
\( \mathrm{P} \)
the circle \( x^{2}+y^{2}=8 \).
W.
Answer the following questions.
The point in the second quadrant from which perpendicular tangents can be drawn to both the parabola and the circle is:
(1) \( (-2,2 \sqrt{3}) \)
(2) \( (-1, \sqrt{2}) \)
(3) \( (-\sqrt{2}, \sqrt{2}) \)
(4) \( (-3,2 \sqrt{3}) \)
