Please help. I posted a minute ago and lost the person who was helping e. I can't figure this out and have graphed. I'm sure it's simple and I'm just not getting it. Analyze and give domain and range of y=log 1/5 (this is the base) x

OpenStudy (anonymous):

\[\large y= log_{\frac{1}{5}}x\]

OpenStudy (anonymous):

The domain and range is the same as all of the other logarithmic functions.

OpenStudy (anonymous):

changing the base doesn't change the nature of the exponentiation, only the scale.

OpenStudy (anonymous):

OK. I knew it was too simple. So I just use the properties of logarithmic functions and stte the domain and range. This can also be converted to \[y=1/5 ^x\]c0rrect

OpenStudy (anonymous):

Or rather \[x = (\frac{1}{5})^y\]
