Chapter 10 Dynamic Graphing III The Dynamic Graph Mode of this calculator gives you real-time representations of changes in a graph as coefficients and terms are changed. It lets you see what happens to a graph when such changes are made. For example, you can see the graph change as illustrated here as the value of coefficient A changes in the formula y = Ax2. y = 2x2 y= 3x2 y - 4x2 10.1 Before Using the Dynamic Graph Mode Highlight the DYNA icon on the Main Menu and then press E.
