How do you find the focal width of a parabola? - Study.com
Web1 The focal width of the parabola ( x − h) 2 = 4 p ( y − k) is 4 p . If you know the vertex, you must know how to transform it to this standard form ( x − 4) 2 = y + 34 So the focal width is 4 p = 1.

WebNov 20, 2013 · The distance between these points is the focal width (which is 4 p ). So, the focal width can be defined simply as the distance between the two arms of the parabola when they have the same y value as the focus.
