Graph the function and determine the amplitude,period,and phase shift.

Question

....     y= -sin(x+pi)-1  

Answer 1

For y = Asin(Bx+C) + D, 

 

    Amplitude = lAl

 

    Period = 2π/ lBl

 

    Phase shift = -C/B

 

So, for the given function, Amplitude = 1, Period = 2π, Phase Shift = -π (π units to the left)
