To sketch: The function by hand without plotting any points and then graph of the function .
The standard graph of the function is roughly drawn is shown below in Figure 1.
Then, draw the graph of by shifting the graph by 1 unit downward. Thus, the graph of is shown below in Figure 2.
From Figure 2, it is observed that Figure 1 is shifted 1 unit to the downward. Then, draw the graph of , by reflecting the portion of the graph that appeared below the x-axis about the origin. Thus, the graph of is shown below in Figure 3.
Observe that Figure 3is obtainedfrom Figure 1 in such a way that it is shifted1 unit downward and then reflected the curve that appear below the x-axis about the origin.
