The ever-increasing amount of carbon dioxide in Earths atmosphere is an area of concern for many scientists. In order to more accurately predict what the future consequences of this could be, scientists make mathematic models to extrapolate past increases into the future. A model developed to predict the annual mean carbon dioxide level L in Earths atmosphere in parts per million t years after 1960 is L(t)=36.9 x e^(0.0223t) +280
A. Use the function L(t) to describe the graph of L(t) as a series of transformations of f(t)=e^t
B. Find and interpret L(80), the carbon dioxide level predicted for the year 2040. How does it compare to the carbon dioxide level in 2015?
C. Can L(t) be used as a model for all positive values of t? Explain.
