Answer:

[tex]y' = (\frac{1}{4})^{x}*\ln{\frac{1}{4}} = -1.3863 *(\frac{1}{4})^{x}[/tex]

Step-by-step explanation:

If we a function in the following format:

[tex]y = a^{x}[/tex]

This function has the following derivative:

[tex]y' = a^{x}*\ln{a}[/tex]

In this problem, we have that:

[tex]y = (\frac{1}{4})^{x}[/tex]

So [tex]a = \frac{1}{4}[/tex]

The derivative is

[tex]y' = (\frac{1}{4})^{x}*\ln{\frac{1}{4}} = -1.3863 *(\frac{1}{4})^{x}[/tex]
