The 3 forms of Quadratic functions

Tick the equation form you wish to explore and move the sliders.[br]Which key features relate directly to each form? (vertex, axis of symmetry, roots, y-intercept)[br]Can the graphs of quadratic functions [u]always[/u] be represented algebraically in the 3 forms? [br]Why or why not?
