Answer:
Step-by-step explanation:
The general form of an exponential equation for growth is
[tex]y=(1+r)^x[/tex]
and for decay is
[tex]y=(1-r)^x[/tex]
In general, if the number inside the parenthesis (the growth or decay rate) is greater than 1, it's a growth problem. If the number inside the parenthesis is greater than 0 but less than 1 (in other words a positive fraction), it's a decay problem.
