Using ODF Custom Shapes to Draw Parabolas
The document "Using ODF Custom Shapes to Draw Parabolas" contains some custom shapes of a parabola. If you want to use one of the shapes, you can simply copy&paste it into your document. For frequent use of the shapes in other documents, you should consider dragging them into your Gallery, so that you don’t need to open the document to get them.
The shapes are all created by directly editing the file source. The document contains some explanations about that, but you can use the shapes without understanding the explanations or having any knowledge on how to create your own custom shape.
The last section in the document describes how to place a parabola shape numerically correctly in a coordinate-system. That might be useful for you in any case.
