Select the correct answer Which equation matches the function shown in the graph A.y=sin(x+pi) B. y=sin(x+pi/2) C.y=sin(x-pi) D. y=(x-pi/2)

Answer:
y= sin(x+pi/2)
Step-by-step explanation:
I graphed all of the answers with a calculator and this equation was the only one that had points above the 2 pi on the x axis.
