A park ranger notices water lilies in a pond. Each day, she graphs how many water lilies she sees in the pond.
1. How many water lilies were in the pond after 2 days?
2. If the water lilies continue to grow in this pattern, how many water lilies will be in the pond after 4 days?
3. Write an equation to represent this relationship:
is the number of days since the ranger began recording.
is the number of water lilies.
