    Graphing complex logartihmic equations with a TI-83+?

    I've searched this on multiple forums and websites, and no info has been given at all. Would like to know of an easier way to graph this rather than performing transformations by hand.

    Example: The logarithmic equation: y =   1/5log_3(9x-36)^1^5 -13
    How exactly would I graph this? I tried the base changing formula, and tried inputting 0.2log(9x-36)^1^5 - 13/log(3) but it didn't give me the correct graph? Any help? Thanks in advance, this really stumped me.

    \displaystyle \frac{log(3)}{log(9x-36)^{15}}-13

    Is that log base 3 quantity to the 15th power or quantity to the 15th power? If it is the latter, this should do it.

    You're also going to have some domain issues, I think. What is the domain of your function?
