What is point [i]A [/i]known as?
By changing the values of [i]h[/i] and [i]k[/i] on the sliders, how does it impact the quadratic curve?
Does the curve always touch the [i]x[/i]-axis?
When we change the value of [i]a[/i] on the slider, what are the [b]impacts[/b] on the quadratic curve? Record your observations.
State the [b]key[/b] features that we can identify from the quadratic curves when it is expressed in (1) general form, (2) factorised form and (3) complete the square form?
