A circle touches the parabola `y^2= 4x` at `(1, 2)` and also touches its directrix. The y-coordinates of the point of contact of the circle and the directrix is-

The radius of the circle touching the parabola y^2=x at (1, 1) and having the directrix of y^2=x as its normal is

Consider a circle with its centre lying on the focus of the parabola, y^2=2px such that it touches the directrix of the parabola. Then a point of intersection of the circle & the parabola is:

Consider a circle with its centre lying on the focus of the parabola, y^2=2px such that it touches the directrix of the parabola. Then a point of intersection of the circle & the parabola is:

If the tangent to the parabola y= x^(2) + 6 at the point (1, 7) also touches the circle x^(2) + y^(2) + 16x + 12y + c =0 , then the coordinates of the point of contact are-
