Answer: 
<u>Step-by-step explanation:</u>
f(x) = A sin (Bx - C) + D
- amplitude = |A|
- period =

- phase shift =
- vertical shift = D
<u>A</u>
amplitude of 3 is given so 3 = |A| → A = ± 3, since it is stated that this is a positive function, then A = 3
<u>B</u>
period of 6π is given so 
<u>C</u>

<u>D</u>
vertical shift of -1 is given so -1 = D
Now, substitute the values of A, B, C, and D into the formula (above):

Next, solve when x = 2π
