The orientation of the vertex focus and directrix allows us to determine the equation of a parabola if we are given certain pieces of information about the vertex focus and directrix The vertex always falls halfway between the focus To calculate the focus of a parabola defined by coordinates x y Find the y coordinate using the formula y c b 1 4a Find the x coordinate using the parabola
The equation of a parabola is obtained by finding and equating the distances between the focus and the point on the parabola and the distances between the directrix and The parabola is the curve formed from all the points x y that are equidistant from the directrix and the focus The line perpendicular to the directrix and passing through the focus that is
