Answer:
y = sin(x+90)
Step-by-step explanation:
The shape of the graph shown is a y = cos x graph
Since that is not an option, we know that it must be translated somewhat
Sin x and cos x graphs are the exact same in shape, but differ by 90°
Y = sin (x+90) is the same as a Y = cos x graph, so Y = sin(x+90) is our answer
