This applet investigates simple Exponential Functions where [b]the base number is two or three[/b].[br]Move the slider to change the value of a, the coefficient in front of the exponential function.[br]You can see the effect of this by comparing the blue graph to the graph of the simple exponential function which is red.[br]Use the buttons to show the table - make sure you understand how the graph changes as you change a. [br]Turn "Trace On" - you will then see copies of the graph as you move the slider.

Examine the values in the table as you move the slider.[br]What effect does changing [i]a[/i] have on the graph?[br]What effect does changing the base number have?
