# (a) How is the graph of y = 2 sin x related to the graph of y =  sin x? Use your answer and Figure 6 to sketch the graph of y = 2 sin x.(b) How is the graph of y = 1 + x related to the graph of y = x ? Use your answer and Figure 4(a) to sketch the graph of y = 1 + x .

(a)

To determine

To sketch: The graph of the function y=2sinx by using the graph of y=sinx and explain how the graph y=2sinx is related to y=sinx .

Explanation

Since 2 multiplied by sinx , stretch the graph y=sinx vertically by a factor of 2. Thus, the graph of y=2

(b)

To determine

To sketch: The graph of the function y=1+x by using the graph of y=x and explain how the graph y=1+x is related to y=x .
