\n" ); document.write( "Hi
\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( " x^2 = 4py p = -3 4p = -12
\n" ); document.write( " x^2 = -12y OR y = -(1/12)x^2
\n" ); document.write( "
\n" ); document.write( " \n" ); document.write( "
