Question

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

Explanation:

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

Answer:

Midline
