Beginning with the function y = sin x, which would have range from -1 to 1 and period of 2pi: Vertical compression of 1/2 compresses the range from -1/2 to 1/2 Phase shift of pi/2 to the left Horizontal stretch to a period of 4pi, as the crests are at -4pi, 0, 4pi Vertical shift of 1 unit up moves the range to 1/2 to 3/2 So the first choice looks like a good answer.
The first choice is the answer: Solution:the function y = sin x, which would have range from -1 to 1 and period of 2pi: So the answer would be:Vertical compression of 1/2 compresses the range from -1/2 to 1/2Phase shift of pi/2 to the leftHorizontal stretch to a period of 4pi, as the crests are at -4pi, 0, 4piVertical shift of 1 unit up moves the range to 1/2 to 3/2
