1) Find the function rule for a linear function G(t) where t is the number of years since 2019 and G(t) is the total greenhouse gasses emitted by the US. Your function should contain the points (0, 6558) and (11, 3711).
If t is the number of years since 2019 the two points that each of the models need to pass through are (0, 6558) and (11, 3711). (This is because 2030 is 11 years after 2019.)
1) Find the function rule for a linear function G(t) where t is the number of years since 2019 and G(t) is the total greenhouse gasses emitted by the US. Your function should contain the points (0, 6558) and (11, 3711).
2) Find the slope of your line and write a sentence that describes what the slope tells us about the rate of change under this scenario.
3) What greenhouse gas emissions does this function predict for 2020 and for 2025?
4) Compare the predicted change in greenhouse gas emissions between 2020 and 2025 to the change between 2025 and 2030? During which five-year period is the predicted change greater and by how much or is it the same in the two-time periods?
5) During what year does this function rule predict that the US emission of greenhouse gasses will decrease to 1000 million metric tons of carbon dioxide equivalents?
