Step-by-step explanation:
Do you mean 
or 
?
Use the formula 
where 
is the amplitude, 
is the phase shift, 
is the vertical shift, and the period is 
.
Assuming your first case is true, the amplitude would be 
, your period is 
, and your midline/vertical shift is 
.
Assuming your second case is true, everything but the vertical shift stays the same. It would be 
in this case.
the answer to this question is -8
