What is the standard form of a parabola that opens upwards?

Back

The standard form is (x - h)² = 4p(y - k), where (h, k) is the vertex and p is the distance from the vertex to the focus.

What is the definition of a directrix in relation to a parabola?

Back

The directrix is a line perpendicular to the axis of symmetry of the parabola, located at a distance p from the vertex, opposite to the focus.

What distinguishes an ellipse from a hyperbola?

Back

An ellipse has a positive discriminant (B² - 4AC < 0), while a hyperbola has a negative discriminant (B² - 4AC > 0).

What is the focus of a parabola?

Back

The focus is a point located p units from the vertex along the axis of symmetry, where all points on the parabola are equidistant from the focus and the directrix.
