Question

Question: Global warming the increase in carbon dioxide (co₂) in the atmosphere is a major cause of global warming. Using data obtained by charles david keeling, professor at scripps institution of oceanography, the average amount of co2 in the atmosphere from 1958 through 2007 is approximated by

A(t) = 0.010716t² + 0.8212t + 313.4               (1 ≤ t ≤ 50)

Where a(t) is measured in parts per million volume (ppmv) and t in years, with t = 1 corresponding to the beginning of 1958.

A. What can you say about the rate of change of the average amount of atmospheric co₂ from the beginning of 1958 through 2007?

B. What can you say about the rate of the rate of change of the average amount of atmospheric co₂ from the beginning of 1958 through 2007?
