Find Where Increasing/Decreasing y=(1/5)^x

$y = {(\frac{1}{5})}^{x}$

Step 1

Simplify ${(\frac{1}{5})}^{x}$ .

Apply the product rule to $\frac{1}{5}$ .

$y = \frac{1^{x}}{5^{x}}$

One to any power is one.

$y = \frac{1}{5^{x}}$

Step 2

Graph the equation in order to determine the intervals over which it is increasing or decreasing.

Always Decreasing
