Answer:
Step-by-step explanation:
Amplitude is twice the coefficent of the sine function. In this case, [tex]2*2=4[/tex]
Period is [tex]2\pi[/tex] divided by the coefficent of x, in this case, [tex] \frac {2\pi} 1 =2\pi [/tex]
Phase shift, is how much you sum or subctract from x inside the sine, in this case [tex] \pi [/tex].
Midline you get by hiding the sine and reading what's left, in this case, -4.
