Definitions:

Parabola

A U-shaped curve, represented mathematically as the graph of a quadratic function.

Vertex

In the context of geometry and graph theory, a vertex is a point where two or more curves, edges, or lines meet. In the context of quadratic functions, it is the highest or lowest point of the parabola.

Intercepts

Points where a graph crosses the axes of a coordinate system, typically identified as x-intercepts (where the graph crosses the x-axis) and y-intercepts (where it crosses the y-axis).

Parabola

A symmetric curve formed by all the points at an equal distance from a point called the focus and a line called the directrix.
