The coordinates of the point on the parabola y2 = 4x with the closest distance to its focus are

The coordinates of the point on the parabola y2 = 4x with the closest distance to its focus are

The distance from the point to the focus on the parabola is equal to the distance from the point to x = - P / 2, so it is at the origin (0,0)

If the distance between the point P on the parabola y2 = 12x and the focus is 8, then the distance from P to the collimator is ()
A. 5B. 6C. 7D. 8

According to the definition of parabola, the distance from point P to focus is equal to the distance from point P to its directrix. If the distance between point P and focus is 8, then the distance from point P to directrix is 8
