\n" ); document.write( "the vertex form of a Parabola opening up(a>0) or down(a<0), \"y=a%28x-h%29%5E2+%2Bk\"
\n" ); document.write( "where(h,k) is the vertex and x = h is the Line of Symmetry
\n" ); document.write( "The standard form is \"%28x+-h%29%5E2+=+4p%28y+-k%29\", where the focus is (h,k + p)
\n" ); document.write( "With Directrix y = -(k+p)
\n" ); document.write( "focus (0,6) and directrix y= -10, p = \"%286-%28-10%29%29%2F2+=+8\" 4p = 32
\n" ); document.write( " y = (1/32)x^2 -2
