1.1. The vertex of a parabola is the lowest or highest point of the parabola.

2. Parabola

2.1. U-shaped curve is called a parabola.

3. Minimum Value

3.1. The minimum value is the y-value of the vertex when the parabola points upwards

4. Quadratic Function

4.1. Quadratic function is a function that can be written in f(x) = a (x – h)²+k(a ≠ 0).

5. Axis of Symmetry

5.1. The axis of symmetry is the line through the vertex of a parabola that divides the parabola into two congruent halves

6. Standard Form

6.1. Standard form can be used to write a quadratic function;f(x)= a x² + bx + c, where a ≠ 0.

7. Maximum value

7.1. The maximum value is the y-value of the vertex when the parabola points downward

8. Zero Function

8.1. A zero function is a value of the input x that makes the output f(x) equal zero. The zeros of a function are the x-intercepts.

9. Completing the square

9.1. If a quadratic expression of the form x²+bx cannot model a square, you can add a term to make a perfect square trinomial. This is called completing the square.

10. Radical Function

10.1. A radical function contains a radical expression with the independent variable (usually x) in the radicand.

11. Translations

11.1. Translations are the things you do to the parent function. They can be reflected across the y-axis or the x-axis, horizontally stretched/compressed, and vertically stretched/compressed.

12. Imaginary Unit

12.1. The imaginary unit or unit imaginary number is a solution to the quadratic equation x² + 1 = 0.

13. Binomial

13.1. A binomial is a quadratic expression with two terms.

14. Zero Product Property

14.1. If the product of two properties equals zero, at least one of the qualities equals zero. This is called the zero product property.

15. Square root property

15.1. To solve a quadratic equation, you can take the square root of both sides. This is called the square root property

16. Trinomial

16.1. A trinomial is a quadratic expression with three terms.
