A particular sound wave can be graphed using the function y = –3 sin x. Find the period of the function. (1 point) Responses period = 2 period = 2 Image with alt text: pi period = –3 period = –3 period = 3 period = 3 period =
The period of a sin function in the form y = A sin(Bx) is given by the formula 2π/B. In this case, the function is y = -3 sin(x), so B = 1.
Therefore, the period of the function is 2π/1 = 2π.
So the correct answer is period = 2π.
