Investigating Exponential Equations

The following is a graph of an exponential equation. Use to sliders to investigate what happens as a, b, and c change. What changes to a, b, and/or make the graph... 1. more narrow or skinny? 2. more wide or fat? 3. move up and down? 4. move left and right? 5. upside down? Generalize: How does changing a, b, and c change the graph? Consider each variable. Be specific and cite evidence.
