1. what is the independent variable?
2. what is the dependent variable?
3. what is an appropriate title?

Explanation:

Step1: Identify independent variable

The variable that is controlled or changed is the number of days. It does not depend on the number of bacteria.

Step2: Identify dependent variable

The number of bacteria depends on the number of days passed. So, the number of bacteria is the dependent variable.

Step3: Determine appropriate title

A title should summarize the relationship. "Number of Bacteria over Days" is appropriate.

Answer:

1. # of Days
2. # of Bacteria
3. Number of Bacteria over Days
