Specification A12 · Paper 1, Paper 2, Paper 3
The smooth curved graph of a quadratic function.
Revise: Graphs of Linear and Quadratic FunctionsThe marked coordinates show the key contrast: the outputs of the linear function change at a constant rate and lie on a straight line, whereas the quadratic coordinates lie on a smooth parabola that bends around a turning point.
Specification A11, A18 · Paper 1, Paper 2, Paper 3
Revise: Quadratic FunctionsThe turning point is where the parabola changes direction. It is the lowest point of an upward-opening parabola or the highest point of a downward-opening parabola. Its coordinates should be given as an ordered pair.
A smooth, curved graph representing a quadratic function, such as .

The smooth, symmetrical curve formed by the graph of a quadratic function.
Revise: Quadratic Graphs: Roots and Turning PointsIts graph is a smooth, symmetrical curve called a parabola.
