1. Exponential and Logistic Modeling
Objective: Students will be able to model exponential growth and decay graphically and algebraically.

2. Exponential Populations
Using percentage Usually it is 1 + percentage this include the original number and increase by the percent 1 – percentage is percent less the original number

3. Finding Growth and Decay Rates
Look at the base of the exponent, this will help to determine growth or decay, also find the percent of growth or decay
A= 0.64%
B.=1.42%

4. Finding Exponential Function
R=.08
Sub into general equation and solve

5. Radioactive decay and Half Life
Only thing that changes here is how you write the exponents, process is still the same Usually exponent is like a fraction

6. Example

7. Using the Calculator to find the Exponential Regression
Type in data from table 3.9 Make a scatter plot We did line of best fit before Try to find the exponential Growth line of best fit

8. Exponential growth
Looking at a graph not limit, but is there
