There are three main characteristics of a parabola. These are:

- Vertex: The point at the apex of a parabola.
- x-intercepts: The point/s at which the parabola intersects or touches the x-axis.
- Focus
- Directrix
- Axis
- Ordinate/Double ordinate
- Latus Rectum
- Face: If the parabola is in the form of the letter 'U', then its face is upwards. If the parabola is the in form of the inverted letter 'U', then its face is downwards.

No x-intercepts: The parabola does not meet the x axis: |

One x-intercept: The parabola touches the x-axis at one point: |

Two x-intercepts: The parabola intersects the x-axis at two points: |
