1. Parabola- The shape of the graph of a quadratic function.

2. Quadratic function- A function that can be written in the form f(x)=ax2+bx+c, Where a, b, and c are real numbers and a =/ 0, or in the form f(x)=a(x-h)2=k, where a,h, and k are real numbers and a =/ 0.

3. Vertex of a parabola- The highest or lowest point on a parabola.

4. Vertex Form- A quadratic function written in the form f(x)=a(x-h)2+K, where a, h, and k are constants and (h,k) is the vertex

5. Axis of symmetry- The line that divides the parabola into two symmetrical halves.

6. Minimum value- The y-value of the vertex when a parabola opens upward

7. Maximum value- The y-value of the vertex when a parabola opens down

8. Zero function-For the function f, any number x such that f(x)=0

9. Root of an equation- Any value of the variable that makes the equation true.

10. Binomial- A polynomial with two terms

11. Trinomial- A polynomial with three terms

12. Completing the squares- A process used to form a perfect-square trinomial.

13. Imaginary unit- The unit in the imaginary number system.

14. Standard form- Ax+By=C, A,B and C are real numbers
