-Exponential growth occurs when the rate of the value increases.
-Exponential decay occurs when the rate of the value decreases.
Y=a(1+r)t
-Exponential decay occurs when the rate of the value decreases.
Y=a(1+r)t
we can solve exponential growth problems by using the general equation y=a(1+r)tReal world problem

similarities!
the similarities between the two is that they both have a constant change.
differences!
the differences between the two is that one of them goes up in a positive direction and the other goes down in a negative direction.

in exponential decay, the original amount decreases by the same percent over a period or time. y=a(1-r)tReal world problem
