[" If "(2,0)" is the vertex and "y" -axis the directrix of a "],[" parabola,then its focus is "]

If (2,0) is the vertex and y-axis is the directrix of a parabola then its focus is

If (4,0) is the vertex , and Y-axis the directrix of a parabola , then its focus is

If the vertex of a parabola is (0,2), directrix on x-axis then its focus is :

The vertex of the parabola is (4,0) and the y -axis is the directrix. Then the focus is

Find the vertex, axis, focus and directrix of the parabola x^2+ 4x + 2y-7 = 0 .

Find the vertex,focus and directrix of the parabola 4y^(2)+12x-12y+39=0

The line x-1=0 is the directrix of a parabola, y^2=kx then Find the vertex, focus,axis of parabola and length of latus rectum of the parabola.
