| Term | Definition |
|---|---|
| Quadratic Function | A function that can be represented in the formπ(π₯)=γππ₯γ^2+ππ₯+π, where π, π, and π are constants. |
| Vertex | The highest or lowest point on the graph of a quadratic function. The vertex has coordinates (β, π). |
| Axis of Symmetry: | A vertical line that passes through the vertex of a parabola, dividing it into two symmetrical halves. |
| Parabola | The πβπ βππππ curve that represents a quadratic function on a graph |
| Maximum Value | The highest point on the graph of a quadratic function, typically associated with a downward-opening parabola. |
| Minimum Value | The lowest point on the graph of a quadratic function, typically associated with an upward-opening parabola. |
| Standard Form | The standard equation form of a quadratic function, π(π₯)=γππ₯γ^2+ππ₯+π. |
| Vertex Form | An alternative equation form of a quadratic function, π(π₯) = πγ(π₯ ββ)γ^2 + π, where (β, π) is the vertex |
| Factor | To express a quadratic expression as a product of two or more binomials. |
| Roots (or Zeros) | The values of π₯ for which the quadratic function π(π₯) equals zero. They are the π₯βπππ‘ππππππ‘π of the graph. |
| Discriminant | The part of the quadratic formula (β = π^2 β 4ππ) used to determine the nature of the solutions (real, complex, etc.). |
| Symmetry | The property of a parabola where it is symmetric about its axis of symmetry. |
