WebFree Parabola calculator - Calculate parabola foci, vertices, axis and directrix step-by-step WebThis is a sideways, or horizontal, parabola (in blue). On this graph, you can see the focus (marked in green) inside the parabola, the vertex (marked in orange) on the graph, the directrix (marked in purple) on the other side of the vertex from the focus, and the axis of symmetry (marked in red) passing through the focus and perpendicular to the directrix. WebKey Concepts. A parabola is the set of all points (x, y) in a plane that are the same distance from a fixed line, called the directrix, and a fixed point (the focus) not on the directrix. The standard form of a parabola with vertex (0, 0) and the x -axis as its axis of symmetry can be used to graph the parabola. ipc ct45b50
