7-144.
1. Use what you learned in class to complete parts (a) through (c) below. 7-144 HW eTool (Desmos). Homework Help ✎

1. Describe what the graph of y = 3sin(x) will look 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?

$\text{The graph of }y = 3\text{sin} \left(\frac{1}{2}x\right)\text{ has an amplitude of 3 and a period of } 4\pi.$

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

See parts (a) and (b).
