The equation of aparabola is `y^2=4xdotP(1,3)` and `Q(1,1)` are two points in the `x y-p l a n edot` Then, for the parabola. (a)`P` and `Q` are exterior points. (b)`P` is an interior point while `Q` is an exterior point (c)`P` and `Q` are interior points. (d)`P` is an exterior point while `Q` is an interior point
