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.
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
Whisker plots is not that hard you just have to no the Quartiles the center of the graph is Q2 the first dot to the left is the lower quartile the last dot to the left is upper quartile so the second dot is Q1 and the 4 dot is Q3
