Performs and visualizes a quadratic interpolation for a given set of points.

Syntax for entering a set of points: `Spaces`

separate x- and y-values of a point and a `Newline`

distinguishes the next point. Hit the button *Show example* to see a demo.

### Points

### Equation

To get the additional information which is required to perform a quadratic interpolation the algorithm considers the first sub-function to be linear.
