Complete the table with the population after different numbers of weeks.

Graph the butterfly population.
Think carefully about how to choose a scale for the axes.

What is the vertical intercept of the graph? What does it tell you about the butterfly population?

About when does the butterfly population reach 50,000?

The graph shows the amount of a chemical in a water sample. It is decreasing exponentially.
Find the coordinates of the points labeled A, B, and C. Explain your reasoning.

The graphs shows the amount of a chemical in a water sample at different times after it was first measured.
Select all statements that are true.

The amount of the chemical in the water sample is decreasing exponentially.

The amount of the chemical in the water sample is not decreasing exponentially.

It is not possible to tell for certain whether or not the amount of the chemical is decreasing exponentially.

When it was first measured, there were 2,000 mg of the chemical in the water sample.

After 4 hours, there were 100 mg of the chemical in the water.
