How do you write the vertex form equation of the following parabola's:
\n" ); document.write( "***
\n" ); document.write( "vertex at origin, directrix: y= -(1/8)
\n" ); document.write( "axis of symmetry: y-axis or x=0
\n" ); document.write( "Basic form of equation: (x-h)^2=4p(y-k), (h,k)=(x,y) coordinates of vertex
\n" ); document.write( "vertex form of equation:y=A(x-h)^2+k,,(h,k)=(x,y) coordinates of vertex
\n" ); document.write( "parabola opens upward:
\n" ); document.write( "p=1/8 (distance from vertex to directrix on the axis of symmetry)
\n" ); document.write( "4p=1/2
\n" ); document.write( "x^2=(1/2)y
\n" ); document.write( "vertex form of equation:y=2x^2
\n" ); document.write( "..
\n" ); document.write( "vertex at origin, directrix: y= (1/4)
\n" ); document.write( "axis of symmetry: y-axis or x=0
\n" ); document.write( "Basic form of equation: (x-h)^2=-4p(y-k), (h,k)=(x,y) coordinates of vertex
\n" ); document.write( "vertex form of equation:y=A(x-h)^2+k,,(h,k)=(x,y) coordinates of vertex
\n" ); document.write( "parabola opens downward:
\n" ); document.write( "p=1/4 (distance from vertex to directrix on the axis of symmetry)
\n" ); document.write( "4p=1
\n" ); document.write( " x^2=-y
\n" ); document.write( "vertex form of equation: y=-x^2
\n" ); document.write( "..
\n" ); document.write( "vertex at origin, focus: (0, 1/8)
