The video tutorial explains how to convert a quadratic function from general form to standard form. It covers the process of creating a perfect square trinomial, identifying the vertex and axis of symmetry, and graphing the parabola. The tutorial also demonstrates finding additional points for a more accurate graph and emphasizes the symmetry of the parabola.

What happens to the parabola if the coefficient 'A' in the standard form is greater than zero?

• The parabola becomes a straight line.

• The parabola opens upwards.

• The parabola does not change.

• The parabola opens downwards.
