Exponential Functions: Graphs
- Tim Brzezinski
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.
