Quadratic: An equation, graph, or data that can be modeled by a polynomial of highest exponent of 2
Parabola: A Ushaped curve, formed by quadratic equations.
Leading coefficient: The coefficient of a polynomial leading term
Discriminant: The number determined from the coefficients of a quadratic equation. It reveals what type of roots the equation has.
Quadratic formula: . Formula for the roots of a quadratic equation
Vertex: The points of maximum curvature.
Axis of Symmetry: The line passing through both the focus and vertex of a parabola. The two side of the graph on either side look like mirror images.
Focus: A fixed point on the interior of a parabola.
Directrix: A line perpendicular to the axis of symmetry.
xintercept: A point at which a graph intersects the xaxis.
yintercept: A point at which a graph intersects the yaxis
