QuestionDetermine the amplitude of the sinusoidal function $y=-3 \sin \left[2\left\{x-\frac{\pi}{3}\right)\right]+1$. a) -3 b) 2 c) 3 d) $\frac{\pi}{3}$

Studdy Solution
Calculate the amplitude by taking the absolute value of $A$:
The amplitude is given by $|A|$.
$$|A| = |-3| = 3$$
The amplitude of the sinusoidal function is $\boxed{3}$.
