    Help on Functions!

    Hi guys im new here, I have a question for an assignment im currently doing it is;Analyse and comment on the features of the graphs of the functions y=log a ^x and y = log a^-x as the value of "a" changes, It should include effects on gradient,domain,range,intercepts and points of interception.

    Help would be appreciated Thanks,

    Where are you stuck? What are you having trouble doing? Choose different values of a. Draw the graphs. Make comment on what you see.

    This has clearly been set by your teacher as an investigative task for you to learn something from.

    Well, since this is your assignment, what have you done? Have you actually graphed them? That should be your first step. A graphing calculator will do that for you or you can graph online at Graph.

    Do you know any "laws of logarithms"? You should be able to simplify log(a^x) and log(a^{-x}) and then graph them.
