WILL MARK THE BRAINLIEST!! What are the amplitude, period, phase shift, and midline of f(x) = 2 sin(x + π) − 4?
xxMikexx [17]

Answer:

Step-by-step explanation:

Amplitude is twice the coefficent of the sine function. In this case, 2*2=4

Period is 2\pi divided by the coefficent of x, in this case, \frac {2\pi} 1 =2\pi

Phase shift, is how much you sum or subctract from x inside the sine, in this case \pi.

Midline you get by hiding the sine and reading what's left, in this case, -4.
