Jill is studying a strange bacterium. When she first looks at the bacteria, there are 1000 cells in her sample. The next day, there are 2000 cells. Intrigued, she comes back the next day to find that there are 4000 cells!
Create a table and a graph for this situation. The inputs (x) are the days that have passed after she first began to study the sample, and the outputs (y) are the number of bacteria cells.
