Write an equation that models the height of the yo-yo over time.
Determine the first two times when the yo-yo is exactly
inches above the ground.
Use the x-values to determine this quantity.
This is the difference in the maximum and minimum heights.
2. Vertical Shift
3. Horizontal Shift
4. b (frequency)
Note: Part (a) is the period and b = 2π<\i>/p
Test your answer in your graphing calculator.
