1. 7.1 Exponential Models Honors Algebra II

2. Exponential Growth: Graph

3. Exponential Function: x is a real number a ≠ 0 b > 0 b ≠ 1 Examples:

4. Exponential Growth b > 1 y-intercept: Domain: Range: Asymptote:

5. Exponential Decay 0 < b < 1 y-intercept: Domain: Range: Asymptote:

6. Graph

8. b> 1 is growth factor 0 < b < 1 decay factor b = 1 + r r is rate of increase or decrease

10. You invested $1000 in a savings account at the end of 6 th grade. The account pays 5% annual interest. How much money will be in the account after six years?

11. Suppose you invest $1000 in a savings account that pays 5% annual interest. If you make no additional deposits or withdrawals, how many years will it take for the account to grow to at least $1500?
