Caroline is playing on a swing at the playground. The swing's motion is shown in the graph below. When f(x) = 0, the swing is at starting position. When f(x) > 0, the swing is in front of the starting position, and when f(x) < 0, the swing is behind the starting position.
The function describing this graph is a transformation of the parent sine function, y = sin x.
Which interval best describes the range of the transformed function?
A.[-70, 70]
B.[-35, 35]
C.[0, 70]
D.[0, 35]
I apologize that I don't have the graph, but I really need help. Could anyone help me?
