We can draw 3 normals to a parabola from a given point as the equation of normal in parametric form is a cubic equation.
The highest or lowest point of the parabola, it is the point that is closest to the focus. The extreme point lies on the axis of symmetry

It is 9.
Because that is how a parabola is defined!
A parabola is NOT a point, it is the whole curve.
All of the points on a parabola define a parabola. However, the vertex is the point in which the y value is only used for one point on the parabola.
A vertex is the highest or lowest point in a parabola.
The extreme point it the highest or lowest point of the parabola (depending if it is concave downwards or upwards). It is the point of the parabola tat is closest to the focus. the extreme point lies on the axis of symmetry.
The point directly above the focus is the vertex of the parabola. The focus is a specific point on the axis of symmetry of the parabola, and the vertex is the point on the parabola that is closest to the focus.

The point on the parabola where the maximum area occurs is at the vertex of the parabola. This is because the vertex represents the maximum or minimum point of a parabolic function.
A parabola has a single focus point. There is a line running perpendicular to the axis of symmetry of the parabola called the directrix. A line running from the focus to a point on the parabola is going to have the same distance as from the point on the parabola to the closest point of the directrix. In theory you could look at a parabola as being an ellipse with one focus at infinity, but that really doesn't help any. ■

The vertex -- the closest point on the parabola to the directrix.
