Forming Quadratics

Academic

Vocabulary

Vocabulary

The process of converting the quadratic equation from the general form to the standard form and is used to solve quadratic equations and graph quadratic functions.

Mathematical sentence that compares two expressions linked by an equals sign.

A relation, such that each element of a set (the domain) is associated with a unique element of another (possibly the same) set (the codomain).

A diagram that exhibits a relationship, often functional, between two sets of numbers as a set of points having coordinates determined by the relationship; also called plot.

The coordinate of a point where a line, curve, or surface intersects an axis.

A section of a cone where a right circular conical surface intersects with a plane parallel to a generating straight line of that surface. Given a point (focus) and a corresponding line (directrix) on the plane, a parabola is the locus of points in that plane that are equidistant from them. It looks like a U or V shape and can open in any direction.

An equation in which one or more of the terms is squared but raised to no higher power, having the general form ax² + bx + c = 0, where a, b, and c are constants. When graphed, this relationship is represented by a parabola (U-shaped curve).

The point at which the two rays making up an angle meet. It is also the point on a parabola where it changes directions. Also called the turning point.

The x-coordinate of a point where a line, curve, or surface intersects the x-axis.

The y-coordinate of a point where a line, curve, or surface intersects the y-axis.
