Answer: Option C

Step-by-step explanation:
Whenever we have a main function f(x) and we want to transform the graph of f(x) by moving it vertically then we apply the transformation:

If  then the graph of k(x) will be the graph of f(x) displaced vertically b units down.
 then the graph of k(x) will be the graph of f(x) displaced vertically b units down.
If  then the graph of k(x) will be the graph of f(x) displaced vertically b units upwards.
 then the graph of k(x) will be the graph of f(x) displaced vertically b units upwards.
In this case we have

We know that this function has its vertex in point (0,0).
Then, to move its vertex 7 units down we apply the transformation:
 .
.
Then the function k(x) that will have its vertex 7 units below f(x) is

 
        
             
        
        
        
Answer:
Step-by-step explanation:
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form  or  
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have
This is the equation of the line in slope intercept form
where
The given equation not represent a proportional relationship, because the line not pass through the origin
In a proportional relationship the value of b (y-intercept) is equal to zero
