1. Should the graph of this situation be linear or curved?

• Is the growth linear or exponential?

1. Create a table and graph for this situation. The inputs are the days that have passed after she first began to study the sample, and the outputs are the numbers of cells of bacteria.

Make a table starting with day $0$. What is the multiplier?
