Once you get to the “2 + 3/x” part, it gets tough from here. Yes, it is true by one look that this gets you negative from one side and positive from the other side. Technically when the limits are not the same from both sides, the limit should not exist, which you are spot on.
But the way the question was phrased “find the limit...” suggests that a limit does exist, so I have no choice but to follow the wordings.
I’m afraid you may have to check with your teacher/tutor/instructor/lecturer on this, but perhaps the limit really does not exist after all.
