Well i havent read the story but from context clues id say its B
![g(x)=5cos((\pi )/(2)x-(3\pi )/(2))-2](https://tex.z-dn.net/?f=g%28x%29%3D5cos%28%28%5Cpi%20%29%2F%282%29x-%283%5Cpi%20%29%2F%282%29%29-2)
generate by: Amplitude:5 Period:4
Phase shift:(3 to the right) Vertical shift:-2
x=3,g(x)= 3
x=4,g(x)= -2
x=5,g(x)= -5
x=6,g(x)= -2
x=7,g(x)= 3
the graph is like cos(x)
