The parabola is in vertex form,
\n" ); document.write( " $\"y=a%28x-h%29%5E2%2Bk\"$ where (h,k) is the vertex.
\n" ); document.write( "Comparing,
\n" ); document.write( "(h,k)=(-8,2)
\n" ); document.write( "The axis of symmetry is then $\"x=-8\"$
\n" ); document.write( "The coefficient of the $\"x%5E2\"$ term is positive, so the parabola opens upward and the value at the vertex is a minimum.
\n" ); document.write( " $\"ymin=2\"$
