Vedclass · Answer

(B) The focus $S$ is at $(0, 0)$.The directrix is the line $x = 2$.The axis of the parabola is the line passing through the focus and perpendicular to the directrix,which is the $x$-axis $(y = 0)$.The vertex $V$ is the midpoint of the segment connecting the focus $(0, 0)$ and the point of intersection of the axis and the directrix.The intersection of the axis $(y = 0)$ and the directrix $(x = 2)$ is $(2, 0)$.The vertex $V$ is the midpoint of $(0, 0)$ and $(2, 0)$,which is $(\frac{0+2}{2}, \frac{0+0}{2}) = (1, 0)$.

If the focus of a parabola is at the origin $(0, 0)$ and the line $x = 2$ is its directrix,what is the vertex of the parabola?
