Quadratic in Turning Point Form

The 3rd form that quadratics can be written in is f(x)=a(x-h)2+k This is called Turning Point Form. You can probably guess from the name what Turning Point form is useful for.

Does "k" change the x or y value of the turning point? As you INCREASE k, what happens to the turning point?

As you INCREASE the value of "h", What does this change about the turning point? Is this behaviour the same or different to the "k" value?

What does changing the "a" value do? Is this similar or different to the other two forms?
