Question

What is the amplitude, period, and phase shift of f(x) = −4 sin(2x + π) − 5?

amplitude = −4; period = 2π; phase shift: x = negative pi over two

amplitude = −4; period = π; phase shift: x = pi over two

amplitude = 4; period = π; phase shift: x = negative pi over two

amplitude = 4; period = 2π; phase shift: x = pi over two
