Answer:
Step-by-step explanation:
You have been asked to find the values in the function:
First, calculate A, called the amplitude, as half the value from peak to peak (from lowtide to high tide):
Then, calculate the vertical shift D as the average value between the high tide and lowtide:
Then, if P is the natural period of the tide, you can calculate B, or the frequency as:
Finally you need to find C or the phase shift thinking that for negative values, the function is shifted (displaced) to the right.
C=-6.75
