In the picture above, the main shape is called a parabola. It is drawn on a coordinate plane. It shows a quadratic formula which is represented by the equation .

When you draw what a formula represents, it is called a graph. Notice how it is decreasing on the left side and increasing on the right side. C is the vertex. In the picture above, Line A is parallel to the x-axis and perpendicular to the y-axis. The y-axis is also the axis of symmetry. This means that the left side of the y-axis is symmetrical to the right side. If you took the picture above and folded the paper on the y-axis, the pictures would be identical.

A function must have a one-to-one relationship. So, for every solution in y, there can only be one solution in x.
