Question

for a sinusoidal function in the form ( y = a sin(bx - c) + d ), what does the ( a ) help us determine?
phase shift
period
amplitude
midline

Explanation:

In the sinusoidal function \( y = A\sin(Bx - C)+D \), the amplitude of the sine function is given by \( |A| \). The mid - line is \( y = D \), the period is \( T=\frac{2\pi}{|B|} \), and the phase shift is \( \frac{C}{B} \).

Answer:

Amplitude
