The team first experiments with changing the position of the curved pit. In the computer program, the vertex begins on the origin, and the curve is modeled by the parent quadratic equation, y = x2.

Match each description with the equation that will create that pit.

Tiles

The curved pit is shifted down 2 units.

The curved pit is shifted right 2 units.

The curved pit is shifted left 2 units.

The curved pit is shifted up 2 units.
