Answer: A = 4    P = π     PS = -π/2

Step-by-step explanation:

y = A sin(Bx - C) + D      where

  • A is the amplitude
  • Period = 2π/B
  • Phase Shift = C/B
  • D is the vertical shift

Given:  y = -4 sin(2x + π) - 3

  • A (amplitude) = 4      the negative sign is a reflection, not amplitude
  • B = 2
  • C = -π
  • D = -3

Amplitude = 4

[tex]\text{Period}=\dfrac{2\pi}{B}\quad =\quad \dfrac{2\pi}{2}\quad =\quad \pi[/tex]

[tex]\text{Phase Shift}=\dfrac{C}{B}\quad =\quad \dfrac{-\pi}{2}\quad =\quad -\dfrac{\pi}{2}[/tex]
