\n" ); document.write( "Standard form of equation for parabola: y=A(x-h)^2+k, (h,k) being the (x,y) coordinates of the vertex.
\n" ); document.write( "For given conic is a parabola that opens downward and has a vertex at (-1,18)
\n" ); document.write( "The line of symmetry is a vertical line thru the vertex. Its equation: x=-1
