1. Exponential Functions Unit 1 Lesson 3 E. Alexander Burt Potomac School

4. Note where they cross – any coincidence there?

5. Look at the table values. Which one is bigger, and when?

7. a x a y = a (x+y)

8. Divide like bases, subtract exponents

9. a x / a y = a (x-y)

10. A power to a power, multiply exponents (a x ) y = a xy

12. a x b x = (ab) x

13. Fraction to a power

14. (a/b) x = a x / b x

15. Remember that all these rules are reversible!

18. y = k a x where k ≠ 0

21. e is a special base for exponential functions and appears frequently in financial and scientific calculations.

22. We will take a closer look at e later on.
