Write a cosine function for the sinusoid

Step 1: Find and maximum and minimum values



Step 2: Identify one cycle of the cosine function on the graph to form the model function



Step 3: Find the amplitude and period. Show your formula and work for credit.



Step 4: Use the period to determine b. Show formula and work



Step 5: Identify the vertical shift, d. Show formula and work


Step 6: Use the graph to identify the phase shift.



Step 7: Use phase shift and be to determine c.(phase shift = -c/b) Show your formula and work
