1. explain how the the algebraic model f(x)= -0.0008x^3 + 5.5305x^2 - 12195x + 9x10^6 with R^2 = 0.99 was determined

b. are there any restrictions on the domain of the function and/or potential limitations on this algebraic model?

c. how can this algebraic model be used to make a prediction on CO^2 gas emissions for 2050?
