1. Start by moving slider a. What happens to the equation and what happens to the curve? (for positive and negative numbers?) 2. Put slider a back to a=1. Move slider b. What happens to the equation and what happens to the curve? (for positive and negative numbers) 3. Put slider b back to b=1. Move slider c. What happens to the equation and what happens to the curve? (for positive and negative numbers) 4. Put slider c back to c=0. Move slider d. What happens to the equation and what happens to the curve? (for positive and negative numbers) 5. Experiment and observe what happens when you combine 2 or more transformations.
