Step 1

The graph of y = –2sin(x/4) is a reflection across the x axis and a horizontal stretching of the graph of y = sin x.

Compare the equation y = –2sin(x/4) with the equation y = A sin (BxC) + D and obtain the value of B as (1/4) and A as –2.

Step 2

The domain of y = sin x is the set of all real numbers and range is [–1,1].

Consider the key points of y = sin x as follows.

Step 3

First obtain the key points of y = sin(x/4) by dividing the first coor...
