The goal of this GeoGebra Augmented Reality modeling challenge is to author 2 surface equations (with domain restrictions) to

**construct a REGULAR OCTAHEDRON !!!**A regular octahedron is one of the 5 main platonic solids. A regular octahedron is made up of 8 faces.**Each face is an equilateral triangle.****Modeling Clues:**Even though there are infinitely many ways to position & size this regular octahedron, for the one in this screencast (below): 1) (0,0,0) serves as its center. 2) Each edge (side of any equilateral triangle) is 6 units long.
