    amplitude = 2

    period is 90 degrees or pi/2 rad

    If is meant y = -2 sin 4x – 1 = -1 - 2sin(4x) then

    phase shift = 0 and

    vertical shift = -1

    If is meant y = -2 sin 4x – 1 = -2 sin(4x – 1) then

    phase shift = -1 and

    vertical shift = 0

    The general solution is

    Amp * sin(w*t - PhaseShift) + Vertical Shift

    Amplitude is 2. Phase shift is 0. Period = 2*pi/w = pi/2. vertical shift is -1.
