Well that is what I was thinking too, but my book gives me the following options: Horizontal stretch by a factor of 2 Vertical stretch by a factor of 2 Vertical shrink by a factor of 1/2 Horizontal shrink by a factor of 1/2 Originally I chose vertical shrink, but it came back wrong, so I did horizontal shrink, and it also came back wrong. So I don't know at this point.

hmm its def horizontal cuz its x/2 Ohhh I see there is one 1 cycle in 720 degrees so its a horizontal stretch by a factor of 2

There is only a half of one cycle in 360 degrees or another way of saying it is that one cycle takes 720 degrees

the graph get stretched instead of taking 360 degrees to finish one cycle it takes 720 degrees to finish the cycle. It takes double the time
