Which domain window settings would be appropriate if you wanted to graph the function below in degrees for exactly 3 periods?y = 4sin(3x)

For y = 4sin(3x), the coefficient 3 makes the period 360° ÷ 3 = 120°. Exactly 3 periods require a domain length of 3 × 120° = 360°. Choice A, from −90° to 270°, spans 360° and is in degrees. The other choices either span a different length or use radians.
