Answer:
The comparison graph is also attached in 3rd figure. In the 3rd figure, the graph with vertex (0, 0) is representing and
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
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 shifted 6 units to the right as compare to the function
.
The comparison graph is also attached in 3rd figure. In the 3rd figure, the graph with vertex (0, 0) is representing and
is represented as being shifted 6 units to the right as compare to the function
.
Slope = 
------------------------
6 - 6 = 0
15 - (-1) = 16
0 / 16 = 0
--------------------------------
You have a slope of 0, meaning that this is a straight horizontal line
------------------------
6 - 6 = 0
15 - (-1) = 16
0 / 16 = 0
--------------------------------
You have a slope of 0, meaning that this is a straight horizontal line
