I have a math portfolio and im not really sure how to do the whole thing. The black text and table are my answers. I cant figure out how to write a rule.
Task 1
Bacteria are the most common example of exponential growth. Select a number between 2 and 10 to represent the hourly growth rate of a certain bacteria. For example, selecting the number 8 would mean that the amount of bacteria will be 8 times greater after every hour.

- Suppose you start with one single bacterium. Make a table of values showing the number of bacteria that will be present after each hour for the first six hours using the hourly growth rate that you selected. Then determine how many bacteria will be present once 24 hours have passed.
- Bacteria
- Time
- 1
- 1
- 4
- 7
- 16
- 13
- 64
- 19
- 256
- 25
- Explain why this table represents exponential growth.
- This table represents exponential growth because the amount of bacteria quadruples every six hours.
- Using this example, explain why any nonzero number raised to a power of zero is equal to one.
- Nonzero numbers raised to zero equal one because going to the power of 0 is like the product of no numbers.
- Write a rule for this table.
- Suppose you started with 100 bacteria, but they still grew by the same growth factor. How would your rule change? Explain your answer.
