3×0=0
3×1=3
3×2=6
3×3=9
....
3×50=150
2x^2 - 2x + 7 = 2(x^2 -x +3) + 1 = 2(x-0.5)^2 + 17/6

The given population models for the trees is given as:
It is required to find which forest will have a greater number of trees after 20 years and by how many.
To do this substitute t=20 in the equations of the models:
Hence, forest A has a greater number of trees after 20 years.
Calculate the difference:
It follows that forest A has a greater number of trees than forest B by 43 trees.
After 20 years, forest A has a greater number of trees than forest B by 43 trees.
