I worked this out to be -1 1594371557480.png x by converting them to the same base. I put it into a desmos to graph but it says thats no correct. Any help would be appreciated.

You are assuming that if [MATH]a^{-1} \le a^x[/MATH], then [MATH]-1\le x[/MATH]. There is no such rule!

Have you considered what happens if the base is negative, or if it is zero? I would probably try splitting the problem into three cases based on that. (You will find that two cases are, in some sense, "simple".)
