Match each equation (left) with the description of how it change (right) from the function y = x2 graphed.

Draggable item		Corresponding Item
y = -x2		Flips to open down
y = 3x2		Becomes taller, vertically stretches
y = x2 + 6		Moves up

1

Match each graph with a quadratic equation that it represents.

Draggable item		Corresponding Item
Graph B		y = -x2 + 3
Graph D		y = (x + 1)(x + 3)
Graph C		y = x2 - 3
Graph A		y = (x - 1)(x - 3)
