Verified Answer :

f(x) = -4sin(2x + π) - 5

Amplitude
A = -π

Period
2π = 2π = π
 B      2

Phase Shift
-C = -π = ≈ 1.57
 B      2

Answer:

Amplitude of the function is 4, period of the function is π and phase shift of the function is \(-\frac{\pi}{2}\).

Step-by-step explanation:

The given function is

\(f(x)=-4\sin(2x+\pi)-5\)              .... (1)

The general form of a sine function is

\(f(x)=A\sin(Bx+C)+D\)            .... (2)

where, |A| is amplitude, \(\frac{2\pi}{B}\) is period, \(-\frac{C}{B}\) is phase shift and D is midline.

From (1) and (2) we get

\(A=-4,B=2, C=\pi,D=-5\)

\(|A|=|-4|=4\)

Amplitude of the function is 4.

\(\frac{2\pi}{B}=\frac{2\pi}{2}=\pi\)

Period of the function is π.

\(-\frac{C}{B}=-\frac{\pi}{2}\)

Therefore the phase shift of the function is \(-\frac{\pi}{2}\).
