I was playing around with Maple and I noticed that.

=1.995455958

I then added some parameters and came up with the following:

For positive a and b, and c>2.

I do not know why this is, but I find it very interesting. The self-root function is the inverse of an infinite order tetration.

combining the above two and leaving out the restriction ad -bc = 0 if needed.

the substitution y = 1/x proves it.

So it does. Neat. Thanks.

I should try this with the full three parameter version.

edit: 1/x substitution checks out for the full thing.
