# 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.
