The equation of the inverse looks correct, but when I checked graphically the domain is different. The approximate decimal values were -0.267 < x < 0.364

It is correct that the inverse function is given by the rule . However, it is incorrect to say that the

**maximal**domain of is the same as the domain of the inverse function. The domain of the inverse function is in fact a subset of the maximal domain.

@OP: To find the domain of the inverse function you should recall that . So*your*job boils down to finding the range of the given function (so it looks like something is left for you to do after all). This job is quite straightforward since you know that f is a one-to-one function ....
