Answer:

Growth

Step-by-step explanation:

Given

$\frac{2}{3}(2.5)^x$

Required

Growth or decay

The general form is:

$y = ab^x$

Such that:

$b = rate$

For b, we have the following conditions:

$b > 1$ ----- Growth

$0$ --- Decay

$b = 1$ ---- None

Compare $\frac{2}{3}(2.5)^x$ to $y = ab^x$

$b = 2.5$

<em>Because 2.5 > 1, then the first condition applies (growth)</em>
