For this case we have functions of the form:
Where
- <em>A: initial amount </em>
- <em>b: rate of change </em>
- <em>x: independent variable </em>
- <em>y: dependent variable </em>
If : the exponential function decreases
if : the exponential function grows
We have then that the following exponential function decreases:
