Question

Explain the effect that "h" has on the function f(x) = a(x − h)2 + k.

Answer 1

You can do this with geogebra.

1) create a slider, name it "h".
2) create another slider, name it "k".

3) Type "a(x-h)^2+k" into the input bar

Then see what changing "h" does to the equation. :)

Answer 2

h = x vertex point and the k = y vertex point. so if h is changed the vertex x point will change and vise versa with the k, which is the y vertex

Answer 3

Here you go. If you have geogebra installed, you just need to click "file", "open" and open this file. :)
