2. discriminant
2.1. is part of the Quadratic Formula that you can use to determine the number of real roots of a quadratic equation
3. standard form
3.1. of a quadratic function is f(x)= ax2 + bx + c, where a ≠ 0.
4. Vertex
4.1. of a parabola is the highest or lest point of the parabola.
4.2. Minimum of a parabola is when the parabola opens upward.
4.3. Maximum of a parabola is when the parabola opens downward
4.4. vertex form of a quadratic function is f(x) = a(x – h)2 + k, where a, h, and k are constants.
5. axis of symmetry
5.1. is the line through the vertex of a parabola that divides the parabola into two congruent halves.
6. transformations
6.1. to the parent function f(x) = x2
