# Can anyone help me find the natural domain and range of$$f(x) = ## Main Question or Discussion Point can anyone help me find the natural domain and range of [tex]f(x) = 1 - log_3x$$
*the whole equation is under a square root sign, its just a couldn't latex it

so it's $f(x) = \sqrt{1 - \log_3{x}}$?

Well, when is $\log_3{x}$ defined? When is $\sqrt{x}$ defined?

Two suggestions to build off of Data's. $\log_3{x} = \frac{\ln{x}}{\ln3}$

and

$$1 - \log_{3}x \geq 0$$
