Answer:
Growth
Step-by-step explanation:
Given
![\frac{2}{3}(2.5)^x](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%282.5%29%5Ex)
Required
Growth or decay
The general form is:
![y = ab^x](https://tex.z-dn.net/?f=y%20%3D%20ab%5Ex)
Such that:
![b = rate](https://tex.z-dn.net/?f=b%20%3D%20rate)
For b, we have the following conditions:
----- Growth
--- Decay
---- None
Compare
to ![y = ab^x](https://tex.z-dn.net/?f=y%20%3D%20ab%5Ex)
![b = 2.5](https://tex.z-dn.net/?f=b%20%3D%202.5)
<em>Because 2.5 > 1, then the first condition applies (growth)</em>
