10-5 Drawing a Dynamic Graph The following is the general procedure you should use to draw a Dynamic Graph. 1. Select or input a function. 2. Define the dynamic coefficient. •This is a coefficient whose value changes in order to produce the different graphs. •If the dynamic coefficient is already defined from a previous operation, you can skip this step. 3. Assign values to each of the' coefficients of the function. 4. Specify the range of the dynamic coefficient. *If the range of the dynamic coefficient is already defined from a previous operation, you can skip this step. 5. Specify the speed of the draw operation. •If the speed is already defined from a previous operation, you can skip this step. 6. Draw the Dynamic Graph. • To set up for a Dynamic. Graph Each of these steps is covered in detail below, using the following example. Example To set up the Dynamic Graph for Y = A (X - 1)2 - 1, as coefficient A changes from 2 to 5 in increments of 1.
