## Question:

The table gives the estimated global carbon dioxide (CO_{2}) emissions from fossil-fuel burning, cement production, and gas flaring over the last century. The CO_{2} estimates are expressed in millions of metric tons.

a. Plot the data, letting x = 0 correspond to 1900. Do the emissions appear to grow linearly or exponentially?

b. Find an exponential function in the form of fx = f_{0}a^{x} that fits this data at 1900 and 2000, where x is the number of years since 1900 and f(x) is the CO_{2} emissions.

c. Approximate the average annual percentage increase in CO_{2} emissions during this time period.

d. Graph and estimate the first year when emissions will be at least double what they were in 2000.
