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
To solve, you need to carry the decimal two spaces to the right because there are two zero in 100 so 0.17 times 100 is 17. The height of the tree after ten years was 17 meters tall in height.
