I would say decay.
Explanation:
We can have a look at the base
this is very good because we see that if you try to use your exponent
So, the fraction
Try with
and:
So our exponential function will return us values that become smaller as
Graphically we see this as:
graph{39(0.098)^x [-11.25, 11.25, -5.625, 5.625]}
Hope it helps!
