Dynamic Views for Increasing and Decreasing for Quadratic
Functions Graphs and Mapping Diagrams
$f(x)= Ax^2 + Bx + C$
- Move the sliders to change the value of $A$, $B$, or $C$.
- 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 $x= -\frac B {2A}$.
- 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.
