i will mark brainlist if correct

Which of the following could be the equation of the function below
y=0.5cos(2(x-pi/2))+2 y=0.5cos(4(x+pi/2))-2 y=0.5cos(4(x+pi))+2 y=0.5cos(2(x-pi))-2

Answer 1

y=0.5cos(2(x-pi))-2 - I Think Usure

Answer 2

Answer:

y=0.5cos(2(x-pi/2))+2 y=0.5cos(4(x+pi/2)) -2

I think that's the answer.
