Expert Solution

Explanation of Solution

The standard graph of the function y=x is roughly drawn as shown below in Figure 1.

Then, draw the graph of y=x+1 , by shift the graph y=x by 1 unit left. Thus, the graph of y=x+1 is shown below in Figure 2.

From Figure 2, it is observed that Figure 1 is shifted 1 unit to the left.

To draw the graph of y=2x+1 , stretch the graph y=x+1 vertically by a factor of 2. Thus, the graph of y=2x+1 is shown below in Figure 3.

Observe that Figure 3is obtainedfrom Figure 1 in such a way that it is shifted 1 unit to the left and then stretched vertically by a factor of 2.
