Question in AP's workspace
Compute a table of values for a quadratic function. A JSXgraph plot shows the curve going through the entered values.

Question in AP's workspace
Compute a table of values for a quadratic function. A JSXgraph (the graph paper) plot shows the curve going through the entered values. The student input is now disconnected from the graph so that they slide the points usually after they input the values and the answer fields are not updated.

Find a regression equation.
Now includes a graph of the regression line and another interactive graph gives users the opportunity to move the regression line around. Could be used for allowing users to experiment with what they think the line should be and see how this compares with the calculated line.
Also includes an updated SSE to see how the sum of the squares of the residuals varies with the regression line.

Write down the Newton-Raphson formula for finding a numerical solution to the equation emx+bx−a=0. If x0=1 find x1.
Included in the Advice of this question are:
6 iterations of the method.
Graph of the NR process using jsxgraph. Also user interaction allowing change of starting value and its effect on the process.

A graphical approach to aiding students in writing down a formal proof of discontinuity of a function at a given point.
Uses JSXgraph to sketch the graphs and involves some interaction/experimentation by students in finding appropriate intervals.

This question involves matching images of graphings to descriptions of the relationships between variables.
-
Match up equations with the corresponding lines on a graph.

Question in Functions and Graphs
This task is part of a set of three assessment tasks for 7.RP.2.
7.RP.2 Robot Races asks students to "explain what a point (x,y) on the graph of a proportional relationship means in terms of the situation" and to "compute unit rates associated with ratios of fractions." Students also need to compare the speeds of the robots.

This question plots a general amplitude modulated carrier signal defined by vs(t)=(VDC+Vmcos(2πfmt))cos(2πfct), where VDC is a DC offset, Vm is the message amplitude, fm is the message frequency and fc is the carrier frequency (fc=20fm in this question). The student must identify the values of VDC and Vm and enter these values into the appropriate gaps in the equation of the AM signal.
