Question

(a) Let x be in years, where corresponds to
2000, to 2001, and so on. Find values for
C and a so that models the data.
(b) Graph f and the data in the same viewing rectangle.
(c) Use to estimate graphically the year when
the carbon dioxide concentration will be double
the preindustrial level of 280 ppm.

year 2000 2050 2100 2150 2200
CO2 364 467 600 769 987

Answer 1

put data in excel and do a scatterplot graph to get an idea of a function to model the data

Answer 2

ok

Answer 3

ok now you can add a trendline, right click on data in graph and pick format trendline. choose polynomial because you can see it increasing like a parabola
