Parameters 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.
