Step 1
Step 1: Recall the key parts of a parabola: the focus is a point inside the parabola; the directrix is a line outside the parabola; the axis of symmetry is the line through the vertex and focus that splits the parabola into mirror images. Show more…

The line through the focus and perpendicular to the directrix is called the _______ of the parabola.
Analytic Geometry
The Parabola
Use the following definition. The line segment that has endpoints on a parabola, passes through the focus of the parabola, and is perpendicular to the axis of symmetry is called the latus rectum of the parabola. Find the latus rectum of any parabola in terms of $|p|$, the distance from the vertex of the parabola to the focus.

Conic Sections
Identify the coordinates of the vertex and focus, the equations of the axis of symmetry and directrix, and the direction of opening of the parabola with the given equation. Then find the length of the latus rectum and graph the parabola. $$ x=-3 y^{2}+1 $$
