Unit 9-3 Agenda
  1. Find the traits given in the word problem
    • Half the distance from max to min is the amplitude
    • The midpoint between max and min is the sinusoidal axis (vertical shift)
    • The period is the time it takes for the model to complete one cycle
    • The horizontal shift is determined by when the graph has its first maximum
