Abstract

I was recently exploring some of the capabilities of GeoGebra. I wanted to set up a general quadratic equation y = ax2 + bx + c and then create sliders which I could move to alter the values for each of a, b and c. I formatted the three sliders so that they could be set at any value from -5 to +5 , moving in increments of 0,1. This proved to be a very effective way of investigating the influence of a, b and c on the graph. What makes it so effective is the dynamic nature of the interaction - as a particular slider is adjusted, the graph on the screen immediately moves to its new position.
