nverse function of log6(x+1)

----------------------------------------------------------------------------------------------------------------------------

I'm assuming that you mean this:   y = log6 (x + 1)

Let's write this in exponential form, we have

6y = (x + 1)           Now get x by itself

6y - 1  = x              Now "exhange" x and y

6x - 1  = y              Now, write y  as f-1(x)

f-1(x) = 6x - 1

Notice that the "log" graph has a restricted domain ......i.e., x > -1

And notice that the range of the inverse is y (or f-1(x))  > -1
