( x - dx/2 ) 3+b.( x - dx/2 ) 2+c.( x - dx/2 ) +dĪ.( x + dx/2 ) 3+b.( x + dx/2 ) 2+c.( x + dx/2 ) +d These two expressions give the value of your cubic functionfor ( x - dx/2 )and ( x + dx/2 )respectively. Using each of these measures and the measures of your four coefficients(a, b, c, and d) create the following two cubic expressions: a. In the calculator create the measure of ( x - dx/2 )and ( x + dx/2 ). In this activity we shall use our control_pt.gssscriptto create a control point that will be used to measure small changes inx. Play with the control points and see how the differentcoefficients affect the shape of the graph of the cubic function. Whileit is selected, change its color using the Display menu.
The locus of the cubic function should appear. Select the plotted point and the point x IN THAT ORDERand choose Locus under the Construct menu. 
If you don’t see the plotted point move your point xcloser to the origin. Select the measure of x and this cubic expression INTHAT ORDER and Plot as (x, y) under the Graph menu. Using the measures of a, b, c and d, and x constructthe following expression in the calculator: a.x 3+b.x 2+c.x+d.(You will need to press the * key between the measure of each coefficientand the measure of x.). Measure the coordinates of x and use the calculatorto get the x-coordinate of x (see step 8 above). Use your script to create four control points labeleda, b, c and d. for point b, edit the measurement to read"b =" rather than "x a =". You willneed to change the labels of each new control point and also edit the measurementfor each control point (e.g. Simply select the y-axis and play your script. You can now use your script to place more control pointsalong the y-axis. Stop your script recording and save the script as control_pt.gss. Double click these coordinates to bring up the calculatorand click once more to get the x-coordinate of point a in the calculator.Click O.K. Construct a segment between your two points (the oneon the y-axis and point a). Place a point on the perpendicular line and change itslabel to "a". Construct a line through this point perpendicular tothe y-axis. Place a point on the y-axis somewhere below the x-axis. Start a new script from the file menu and click therecord button. Once youhave your script use it to construct a control point for each coefficientneeded for your particular function. The followingsteps can be used to construct dynamic graphs of most functions.First you need to create a script for constructing control pointsthat will be used for varying the coefficients of your function. To construct a graph of a function start by selecting CreateAxes from the graph menu. 3.0 it is possibleto construct the graph of almost any algebraic function using the Plotas (x, y) feature under the Graph menu and the Locusconstruction under the Construct menu.
