2. Vertex

2.1. of a parabola is the highest or lest point of the parabola.

2.2. Minimum of a parabola is when the parabola opens upward.

2.3. Maximum of a parabola is when the parabola opens downward

2.4. vertex form of a quadratic function is f(x) = a(x – h)2 + k, where a, h, and k are constants.

3. axis of symmetry

3.1. is the line through the vertex of a parabola that divides the parabola into two congruent halves.

4. discriminant

4.1. is part of the Quadratic Formula that you can use to determine the number of real roots of a quadratic equation

5. standard form

5.1. of a quadratic function is f(x)= ax2 + bx + c, where a ≠ 0.

6. transformations

6.1. to the parent function f(x) = x2
