To sketch: The function by hand without plotting any points.
The standard graph of the function is roughly drawn as shown below in Figure 1.
From Figure 1, it is observed that the curve intersects the x-axis at the point .
Since the number 3 is subtracted from x in , shift the graph by 3 units to the right.
Thus, the graph of is shown below in Figure 2.
From Figure 2, it is observed that the curve intersects the x-axis at the point .
