Identify Function & Period: Identify the basic function and its period.The basic function here is sine, which has a standard period of 2π for sin(x). The period of sin(bx) is given by ∣b∣2π, where b is the coefficient of x.
Determine Coefficient of x: Determine the coefficient of x in the given function.In the function g(x)=−sin(−8x−3)+5, the coefficient of x is −8.
Calculate Period: Calculate the period of the given function.The period of g(x) is 2π divided by the absolute value of the coefficient of x, which is ∣−8∣. Therefore, the period is ∣−8∣2π=82π=4π.
Verify Transformations: Verify that the transformations do not affect the period.The transformations in the function include a reflection, a horizontal shift, and a vertical shift. None of these transformations affect the period of the sine function. Therefore, the period remains 4π.
