Find Amplitude Coefficient: The amplitude of a trigonometric function like y=Asin(Bx−C)+D is the absolute value of the coefficient A. In this case, the function is y=−sin(8x−3)+5, so the coefficient A is −1.
Calculate Absolute Value: The amplitude is the absolute value of −1, which is 1. This means that the amplitude of the function y=−sin(8x−3)+5 is 1 unit.
