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,
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 and and then graph them.
