Step-by-step explanation:
One such polynomial might be

Another with the same roots would be
1. +
2.divide
3. *
4. Divide
5. -
6. +
7. -
8.*
9. 2 and 5
If they are proportional, then y/x should always be the same.
So 9/2= 4.5
We need to find the y value at x=3 to make y/x equal 4.5
4.5 = y/3
y = 4.5*3 = 13.5
