5.3.1 • Creating a Pictorial Representation of Exponential Growth

Warm Up

Bacteria viewed through a microscope.

There are some bacteria in a dish. Every hour, each bacterium splits into 3 bacteria.

1.

This diagram shows a bacterium in hour 0 and then hour 1. Draw what happens in hours 2 and 3.

The picture shows 1 bacterium (an irregular polygon with a double outline and light blue inside) for hour 0, then an arrow to the right, then 3 bacteria for hour 1.

Your answers may vary, but here is an example:

A continuation of bacteria growth from hour 2 with 9 cells and hour 3 with 27 cells.
2.

How many bacteria are there in hour 2?

There are 9 bacteria in hour 2.

3.

How many bacteria are there in hour 3?

There are 27 bacteria in hour 3.
