Answer 2

Answer with explanation:

It is given that:

At an ocean depth of 8 meters, a buoy bobs up and then down 5 meters from the ocean's depth.

Sixteen seconds pass from the time the buoy is at its highest point to when it is at its lowest point.

Assume at x = 0 the buoy is at normal ocean depth.

this means that when x=0 the value on the y-axis is -8.

Also, the buoy bobs up 5 meters up so the maximum height reached by him is -3.

( Since -8+5=-3)

So, the sine function that will represent this situation  is:

$f(x)=5\sin(\dfrac{\pi x}{32})-8$

Now, the graph of this situation is attached to the answer and the mid-line and the first and the second points on it are labelled.
