Answer:
<em>The value of y when x has a value of 9 is 18</em>
Step-by-step explanation:
<u>Functions</u>
The variables x and y are said to have a quadratic relationship. That information is not enough to set up a general equation for both variables.
Furthermore, we know that tripling the value of x causes the value of y to be multiplied by 9. That leads us to establish a proportional equation between them, as follows:

Where k is an unknown constant.
Let's use the given point (3,2) to find the value of k:


Solving for k:

The equation is now:

Now find y when x=9:


The value of y when x has a value of 9 is 18

Thus, the answer is a+ba=1
