Copy of Exponential Functions: Graphs
The following applet displays the graph of the exponential function .  
Interact with the applet below for a few minutes, then answer the questions that follow.  
Questions:
1) How does the parameter a affect the graph of the exponential function?  Explain.  
    What happens if a > 1 and k > 0?  What happens if a < 1 and k > 0? 
2) How does the parameter k affect the graph?  Explain. 
    If you need a hint, refer back to this worksheet.   
3) What does the parameter d do the graph?  Explain.  
4) Suppose a < 1.  
    Given this constraint, is it possible to get the graph of this exponential function to look the way it does
    when a > 1 and k > 0?  Explain.
