Question 36636: I have to expalin this questions and it's very hard for me. Could you please help me out?
Thanks!!!
Do exponential functions only model phenomena that grow, or can they also model phenomena that decay? Explain what is different in the form of the function in each case.

You can put this solution on YOUR website!
They explain both.
The equation for exponential growth is: y=a%281%2Br%29%5Et where y is the total amount, a is the initial amount, r is the rate, and t is the time
This equation can be used for bacteria growth.
The equation for exponential decay is: y=a%281-r%29%5Et with the same idea
This equation can be used for finding the value of car that is constantly used.
There are more equations, but these are basic.
