The percentages of Earth?s land surface that is forested and worldwide carbon dioxide emissions are shown in Table 59 for various years.

Let x be the percentage of Earth?s land surface that is forested and y be worldwide carbon emissions (in billion tonnes).
a. Construct a scatterplot.
b. Find the exponential regression equation.
c. Graph the exponential regression equation on the scatterplot. Explain why the curve is below so many of the data points.
d. Remove the data points (31.4, 24.8) and (31.4, 25.7) and then find the exponential regression equation.
e. Determine whether the data points (31.4, 24.8) and (31.4, 25.7) are influential. Explain.
