SITE-A teams: Lesson 8

A certain culture of bacteria doubles every hour. This type of growth is commonly called exponential growth and it is quite rapid.

Can you develop a table that displays what the bacteria count is every hour given an initial bacteria count of 100 and allowing the growth to take place over the next 10 hours?

Let X represent the time (in hours) over which the bacteria is allowed to grow, and let Y be the bacterial count.

Turn on the **CASIO fx7400G.**

Use your cursor arrows to highlight the TABLE menu and press or just press when at the main menu screen.

On an available Y-slot enter
the expression 2^{x} (100) and press

(Make sure no other Y-slot is highlighted, i.e. selected for computation.).
