# Quadratic functions formula

**Keywords:** quadratic functions formula

**Description:** Refer to this quadratic function tutorial to learn the properties of quadratic functions. Learn domain, range, vertex, x intercepts, and parabola of quadratic functions.

A marathon of tension-filled reality shows can’t deliver the drama of quadratic functions. Peaks, valleys, hitting rock bottom – these plot twists do not exclusively belong to Hollywood. Quadratic functions depict the changing behavior of a set of data. Refer to the graph, *Pop Star’s Record Sales* .

Two years later, the pop fizzled and she sold zero records. Algebra can depict a rags to riches to rags spectacle better than any melodrama.

7. An **axis of symmetry** (also known as a **line of symmetry** ) will divide the parabola into mirror images.

8. The *x***-intercepts** are the points at which a parabola intersects the *x* -axis. These points are also known as **zeroes**. **roots**. **solutions**. and **solution sets**. Each quadratic function will have two, one, or no *x* -intercepts.
