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 as shown below in Figure 1.
Then, draw the graph of by reflecting the graph about x-axis as it is an odd function. Thus, the graph of is shown below in Figure 2.
From Figure 2, it is observed that Figure 1 is reflected about the origin.
To draw the graph of , shift the graph by 2 units upward. Thus, the graph of is shown below in Figure 3.
Observe that Figure 3is obtainedfrom Figure 1 in such a way that it is reflected about the x-axis and then shifted 2 units upward.
