Answer:

Step-by-step explanation:

The general form of an exponential equation for growth is

$y=(1+r)^x$

and for decay is

$y=(1-r)^x$

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.
