write an equation for the conic section
\n" ); document.write( "parabola with vertex at(0,0) and directrix x = 5
\n" ); document.write( "***
\n" ); document.write( "This is a parabola that opens leftward.
\n" ); document.write( "Its basic form of equation: (y-k)^2=-4p(x-h), (h,k)=(x,y) coordinates of the vertex
\n" ); document.write( "For given parabola:
\n" ); document.write( "given vertex: (0,0)
\n" ); document.write( "axis of symmetry: y=0 or x-axis
\n" ); document.write( "p=5 (distance from vertex to directrix on the axis of symmetry)
\n" ); document.write( "4p=20
\n" ); document.write( "Equation: y^2=-20x
\n" ); document.write( "
\n" );
