The scatterplot to the left depicts the carbon dioxide (CO2) concentration, in parts per million (ppm) above 250 ppm, in Earth's
atmosphere between the years 1850 and 2000. Which of the following
functions best models y, the CO2 concentration above 250 ppm, 3
years after 1850 ?
y = -0.00522 - 0.296x - 39.430
y = -0.00522 - 0.296x + 39.430
y = 0.005x2 - 0.2962 – 39.430
y = 0.005x2 - 0.2962 + 39.430
I would be guessing.
