Exponential Functions Predictions

The exponential function modeled represents the number of square kilometers of land occupied by a lizard, x years after the lizard was first introduced into the area. Based on the data shown, which measurement is closest to the number of square kilometers of land that will be occupied by this lizard 40 years after the lizard was first introduced into this area?

• 550,000 km²

• 1,250,000 km²

• 600,000 km²

• 800,000 km²
