Vertex- if a parabola opens upward, the vertex is a point whose y-coordinate us the minimum y-value, or lower bound.
\n" ); document.write( "In this case it is (-1,5)
\n" ); document.write( "The line of symmetry is the line dividing the parabola exactly in half.
\n" ); document.write( "Since it opens upward it is a curve with a minimum value, which is the lowest point of the parabola.
