Question
A parabola has the origin as its focus and the line x=2 as the directrix. Then the vertex of the parabola is at
Solution
The vertex of the parabola is halfway between the focus and the directrix. Given that the focus is at the origin (0,0) and the directrix is the line x=2, the vertex is at the point (1,0).
