A population of amoebas in a petri dish will triple in size every hour. At the start of an experiment the population is 800. The function y equals 800 times 3 to the power of x , where x is the number of hours, models the population growth. How many amoebas are in the petri dish after 9 hours?

Answer:

15,746,400

Explanation:

This is an example of an exponential function.

1. The function is:
800 * 3^(x)

2. We can plug the number of hours into the equation.

3. population = 800 *
3^(9)

4. population = 15,746,400
