Find focus of parabola
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. WebThe focus of a parabola can be found by adding to the x-coordinate if the parabola opens left or right. Step 5.2 Substitute the known values of , , and into the formula and …
