Answer:
The comparison graph is also attached in 3rd figure. In the 3rd figure, the graph with vertex (0, 0) is representing  and
 and  is represented as being shifted 6 units to the right as compare to the function
 is represented as being shifted 6 units to the right as compare to the function  .
.
Step-by-step explanation:
When we Add or subtract a positive constant, let say c, to input x, it would be a horizontal shift.  
For example:
Type of change               Effect on y = f(x)
 horizontal shift: c units to right
                      horizontal shift: c units to right
So 
Considering the function

The graph is shown below. The first figure is representing  .
.
Now, considering the function

According to the rule, as we have discussed above, as a positive constant 6 is added to the input, so there is a horizontal shift, 6 units to the right. 
The graph of  is shown below in second figure. It is clear that the graph of
 is shown below in second figure. It is clear that the graph of   is shifted 6 units to the right as compare to the function
  is shifted 6 units to the right as compare to the function  .
