Select the correct answer. Which equation matches the function shown in the graph?

Answer:

B) $y=sin(x+\frac{\pi}{2})$

Step-by-step explanation:

Technically, since the function starts at its maximum, you could say the function is $y=cos(x)$ , but the answer choices all use sine instead. Therefore, we will have to use the cofunction identity $cos(x)=sin(x+\frac{\pi}{2})$ and we can see that the correct answer is B.
