The graph below has a turning point (3, -2). Write down the nature of the turning point and the equation of the axis of symmetry.

Quadratic equations are basic to algebra and are the math behind parabolas, projectiles, satellite dishes and the golden ratio.

The coordinates of the turning point and the equation of the line of symmetry can be found by writing the quadratic expression in completed square form.
