1. Exponential Growth & Decay

2. Objectives Determine the multiplier for exponential growth and decay.
Write and evaluate exponential expressions to model growth and decay situations.

3. An exponential expression has a fixed base and a variable exponent.
ex: 3n
The base is referred to as the multiplier.

4. Find the multiplier for each rate of exponential growth or decay.
1. 5.5% growth % growth

5. Find the multiplier for each rate of exponential growth or decay.
3. 3% decay % decay

6. Given x = 5, y = and z = 3.3, evaluate and round to nearest tenth.
1. 3y 2. 50(2)3x 3. 10(2)z (2)y
