In 2006, there were approximately 233 million cell phone subscribers in the United states. During the next 4 years, the number of cell phone subscribers increased by about 6% each year. Make a table of this (you can just write 233 and state that y-values are in millions so you don’t have to write out all of those zeros).

Write an equation that would model this situation for these 4 years

Is this situation exponential growth or decay? How can you tell?

What types of multipliers show growth? What types of multipliers show decay?
