a)What is the relation between the graphs of y=log_6 x and y= log_(1/6) x ?
b)which transformation can be applied to the graph of y=log_(1/6) x to obtain the image as the graph of y=6^x ?
thanks!

✔ 最佳答案
(a) y = log_6 x = logx/log6y = log_1/6 x = logx/log(1/6) = -logx/log6
So, the relation is the log_(1/6) x = - log_6 x
(b) First, reflect log_(1/6) x about the x-axis. Then reflect this graph about y = x to obtain y = 6^x
