Answer 3

Help. I'm being repressed.

Answer 4

really ?!!

Answer 5

sin(Ax + b) + c
has a period compression of A, phase shift of b, and vertical shift of c

Answer 6

Inside the parenthesis, whatever x is multiplied by gives you a phase compression, whatever is added or subtracted gives you a phase shift.
Outside the parenthesis, whatever Sin is multiplied by changes the amplitude, and whatever is added or subtracted gives you a vertical shift.
