ANSWER

EXPLANATION
Let the function that represent the graph be:

The parabola passes through the points (-2,8), (0,2), and (1,5).
These points must satisfy the function.
For (-2,8), we have

This implies that that,

For (0,2), we have,

This implies that,

For (1,5), we have

This implies that,

Put c=2 into equation (1) and (2).







Add equation (3) and equation (4)


Put a=2 into equation (4).


Therefore the function is

Find the difference in the two numbers you're comparing and then divide that number by the original number and multiply by 100. it should give you the percentage of the value im not sure how to add the years in there.

GCF=3x^2y
so
3x^2y(2x-3y+1)
