Dynamic Views for Quadratic Functions Graphs and Mapping Diagrams
$q(x)= A(x-h)^2 + k$
- Move the slider to change the value of $A$, $h$, or $k$.
- Select the point $x$ in the mapping diagram to move the point
by mouse or use the scroll up or down key to move by
increments of 1.
Showing Composition of Quadratic:
Check the box to see a second point and the related arrow on
the mapping diagram and triangle on the graph that illustrates
the "slope" of the secant line when $\Delta x = 1$. Notice the
connection between this slope and $A$ when $x = h$.
