Directrix of a Parabola Alineperpendicularto theaxis of symmetryused in the definition of aparabola. A parabola is defined as follows: For a givenpoint, called thefocus, and a given line not through the focus, called thedirectrix, a parabola is thelocusof points such that the distance to th...
What is the equation to find the directrix of a parabola? The directrix of the parabola is the horizontal line perpendicular to the axis of symmetry. If the axis of symmetry is {eq}x- {/eq} axis, then the directrix of the parabola with the focus {eq}a {/eq}, and the vertex {eq...
If (2,0) is the vertex and y-axis the directrix of a parabola then its focus is View Solution Knowledge Check If (2,0) is the vertex and the y− axis is the directrix of a parabola, then where is its focus? A(2,0) B(−2,0) C(4,0) D(−4,0)Submit If (2,0) ...
However there is a more technical definition of a parabola that has to do with a special point, called the focus of the parabola, and a special line, called the directrix of the parabola.Answer and Explanation: The directrix of a parabola is a line for which every point on the parabola ...
. The parabola comprises equidistant points from the focus (single point of the parabola) and the directrix (line of the parabola). Vertex is a special point where the parabola has a change in its direction, thus making it the highest or the lowest point on the graph of the parabola....
The directrix of a parabola is a line perpendicular to the axis of symmetry of the parabola. In a parabola that opens upward in the direction of the positive y-axis, the directrix of the parabola is a horizontal line. Answer...
