Graph each of the functions and describe the graphs (analyze).
Decide if it is an exponential growth or decay function.
How are the similar and how are they different? 1. y = 2x
2. y = (1/2)x
3. y = 3x
4. y = (1/3)x
5. y = 4x
6. y = (1/4)x 4 pc ch 3 3.1 notes day 1.notebook November 20, 2013 Analyze for 1 6
