Answer:
<em>Last option </em>

Step-by-step explanation:
The general sine function has the following form

Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.
is the period: time it takes the wave to complete a cycle.
k is the vertical displacement.
phase shift
We know that:
amplitude: 1; period: 2; phase shift: 3; vertical shift: 4
Thus:





Then the function is:

The answer is last option
The answer is 27.1052631579 or 27.1 if you rounded "m" to .10
