How can I determine what quadrants $\displaystyle y = log_4(x)$ lies in?
I know that this is equivalent to $\displaystyle 4^y = x$ but is there a way I can put that into terms of y so I can plug it into the graphing calculator?
Thanks!

$\displaystyle y = \log_b{x}$ has domain $\displaystyle x > 0$ and a range of all real numbers ... what quadrants would that be?
for graphing purposes, note the change of base formula ...
if $\displaystyle y = \log_b{x}$ , then $\displaystyle y = \frac{\log(x)}{\log(b)}$
... where log is base 10 or base e (your choice on the calculator)
also, note that the new operating system for the TI-84 will graph logs for any base.
