9-122.
  1. Use what you have learned about transformations of y = sin(x) to complete parts (a) through (c). 9-122 HW eTool (Desmos). Homework Help ✎

    1. Describe what the graph of y = 3sin looks like compared to the graph of y = sin(x).

    2. Sketch both graphs on the same set of axes.

    3. Explain the similarities and differences between the two graphs.

Is there a horizontal or vertical shift? Does the amplitude or period change?

Amplitude 3, period 4π

Since there is no horizontal or vertical shift, both graphs start at (0,0).

See parts (a) and (b).
