Graph Explorer (v111) - Alternate Versions

The basic elements of the GraphExplorer can be rearranged to give a different appearance, and particular graph content can be pre-loaded, with user options restricted when the goal is to support a particular instructional activity.

For example:

Line Drawing Spot Hitter This version includes a button to generate and display a random pair of points for the student to pass a line through by setting parameters.
Quadratic Matching Quadratic Matching This one pre-loads both a random quadratic function and the general form f(x)=a*x^2+b*x+c and asks the user to vary a, b, and c to match the two.
Shifting and Scaling Shifting and Scaling
Here the user is allowed to enter a function and can then select which of several scalings and translations to display (with a slider to control the size of the shift or scale parameter).
Secant and Tangent Lines Secant and Tangent Lines and this one places two slideable "beads" on the graph of a pre-loaded function and displays the secant line joining them (along with its rise, run, and slope).
